+# Add-to-App Samples
+
+This directory contains Android and iOS projects that import and use a Flutter
+module. They're designed to show recommended approaches for [adding Flutter to
+existing Android and iOS apps](https://docs.flutter.dev/add-to-app).
+
+## Samples Listing
+
+* [`fullscreen`](./fullscreen) — Embeds a full screen instance of
+  Flutter into an existing iOS or Android app.
+* [`prebuilt_module`](./prebuilt_module) — Embeds a full screen
+  instance of Flutter as a prebuilt library that can be loaded into an existing
+  iOS or Android app.
+* [`plugin`](./plugin) — Embeds a full screen Flutter instance that
+  is using plugins into an existing iOS or Android app.
+* [`books`](./books) — Mimics a real world use-case of embedding Flutter into an
+  existing Android app and demonstrates using
+  [Pigeon](https://pub.dev/packages/pigeon) to communicate between Flutter and
+  the host application.
+* [`multiple_flutters`](./multiple_flutters) — Shows the usage of the Flutter
+  Engine Group APIs to embed multiple instances of Flutter into an existing app
+  with low memory cost.
+* [`android_view`](./android_view) — Shows how to integrate a Flutter
+  add-to-app module at a view level for Android.
+
+## Goals for these samples
+
+* Show developers how to add Flutter to their existing applications.
+* Show the following options:
+  * Whether to build the Flutter module from source each time the app builds or
+    rely on a separately pre-built module.
+  * Whether plugins are needed by the Flutter module used in the app.
+* Show Flutter being integrated ergonomically with applications with existing
+  middleware and business logic data classes.
+
+## Installing Cocoapods
+
+The iOS samples in this repo require the latest version of Cocoapods. To make
+sure you've got it, run the following command on a macOS machine:
+
+```bash
+sudo gem install cocoapods
+```
+
+See https://guides.cocoapods.org/using/getting-started.html for more details.
+
+## Debugging
+
+You can `flutter attach` to the running host application to [debug the Flutter
+module](https://docs.flutter.dev/add-to-app/debugging). This will
+allow you to hot reload, set breakpoints, and use DevTools and other debugging
+functionality, similar to a full Flutter app.
+
+## Issues
+
+If you run into an issue with the sample itself, please file an issue
+in the [Flutter samples repo](https://github.com/flutter/samples/issues).
+
+
+## Updating Android samples and its dependencies
+
+1. Open the top level build.gradle file in Android Studio
+2. Open “Upgrade Assistant” and click upgrade
+
+### Troubleshooting Android updates
+
+* If after upgrading it fails to build, try upgrading to a slightly less new version
+* If there's an "Unknown class version exception <VERSION NUMBER>"  try setting the version of Java used by modifying JAVA_HOME
+* If it still fails to build, check that the Flutter code referenced in the build is up-to-date and doesn't use discontinued plugins. (Common cases include “namespace”)
+* The 'project structure' -> 'modules' view can be helpful in understanding the dependency tree.
+* Once the app builds with the latest gradle/agp, update any deprecated usages in app/build.gradle
+
+* compileSdkVersion -> sdkVersion
+* Update the target sdk version and read through each target sdk update
+* Export broadcast receivers
+* Update the way flutter is imported to use flutter gradle plugin
+* https://flutter.dev/go/flutter-gradle-plugin-apply
+
+* **When updating an app that uses AAR as a Flutter module** -- In android studio update any android dependencies that are indicated as in yellow as old. Keep `androidx.test:runner`, `androidx.test.espresso:espresso-core`, and `androidx.test:core`, as defined in https://github.com/flutter/packages/tree/main/packages/espresso

+# android_view
+
+An example of an Android app that integrates a Flutter add-to-app module at a
+view level.
+
+## tl;dr
+
+If you're just looking to get up and running quickly, these bash commands will
+fetch packages and set up dependencies (note that the above commands assume
+you're building for both iOS and Android, with both toolchains installed):
+
+```bash
+  #!/bin/bash
+  set -e
+
+  cd flutter_module_using_plugin/
+  flutter pub get
+
+  # For Android builds:
+  open -a "Android Studio" ../android_view # macOS only
+  # Or open the ../android_fullscreen folder in Android Studio for other platforms.
+```
+
+## Getting Started
+
+For more information about Flutter, check out
+[flutter.dev](https://flutter.dev).
+
+For instructions on how to integrate Flutter modules into your existing
+applications, see Flutter's
+[add-to-app documentation](https://flutter.dev/docs/development/add-to-app).

+ *  This is an application-specific wrapper class that exists to expose the intersection of an

+ *  rendering.
+ *
+ *  Omitted features from the [io.flutter.embedding.android.FlutterActivity] include:
+ *   * **State restoration**. If you're integrating at the view level, you should handle activity
+ *      state restoration yourself.
+ *   * **Engine creations**. At this level of granularity, you must make an engine and attach.
+ *      and all engine features like initial route etc must be configured on the engine yourself.
+ *   * **Splash screens**. You must implement it yourself. Read from
+ *     `addOnFirstFrameRenderedListener` as needed.
+ *   * **Transparency, surface/texture**. These are just [FlutterView] level APIs. Set them on the
+ *      [FlutterView] directly.
+ *   * **Intents**. This doesn't do any translation of intents into actions in the [FlutterEngine].
+ *      you must do them yourself.
+ *   * **Back buttons**. You must decide whether to send it to Flutter via
+ *      [FlutterEngine.getNavigationChannel.popRoute()], or consume it natively. Though that
+ *      decision may be difficult due to https://github.com/flutter/flutter/issues/67011.
+ *   * **Low memory signals**. You're strongly encouraged to pass the low memory signals (such
+ *      as from the host `Activity`'s `onTrimMemory` callbacks) to the [FlutterEngine] to let
+ *      Flutter and the Dart VM cull its own memory usage.
+ *
+ * Your own [FlutterView] integrating application may need a similar wrapper but you must decide on
+ * what the appropriate intersection between the [FlutterView], the [FlutterEngine] and your
+ * `Activity` should be for your own application.

+ *  This is an application-specific wrapper class that exists to expose the intersection of an
+ *  application's active activity and an application's visible view to a [FlutterEngine] for
+ *  rendering.
+ *
+ *  Omitted features from the [io.flutter.embedding.android.FlutterActivity] include:
+ *   * **State restoration**. If you're integrating at the view level, you should handle activity
+ *      state restoration yourself.
+ *   * **Engine creations**. At this level of granularity, you must make an engine and attach.
+ *      and all engine features like initial route etc must be configured on the engine yourself.
+ *   * **Splash screens**. You must implement it yourself. Read from
+ *     `addOnFirstFrameRenderedListener` as needed.
+ *   * **Transparency, surface/texture**. These are just [FlutterView] level APIs. Set them on the
+ *      [FlutterView] directly.
+ *   * **Intents**. This doesn't do any translation of intents into actions in the [FlutterEngine].
+ *      you must do them yourself.
+ *   * **Back buttons**. You must decide whether to send it to Flutter via
+ *      [FlutterEngine.getNavigationChannel.popRoute()], or consume it natively. Though that
+ *      decision may be difficult due to https://github.com/flutter/flutter/issues/67011.
+ *   * **Low memory signals**. You're strongly encouraged to pass the low memory signals (such
+ *      as from the host `Activity`'s `onTrimMemory` callbacks) to the [FlutterEngine] to let
+ *      Flutter and the Dart VM cull its own memory usage.
+ *
+ * Your own [FlutterView] integrating application may need a similar wrapper but you must decide on
+ * what the appropriate intersection between the [FlutterView], the [FlutterEngine] and your
+ * `Activity` should be for your own application.

+# books
+
+Mimics a real world use-case of embedding Flutter into an existing Android app
+and demonstrates using [Pigeon](https://pub.dev/packages/pigeon) to communicate
+between Flutter and the host application.
+
+## Description
+
+These apps integrate the `flutter_books` module using the simpler build-together
+project setup. They simulate a mock scenario where an existing book catalog
+list app already exists. Flutter is used to implement an additional book details
+page.
+
+* Similar to [`fullscreen`](../fullscreen).
+* An existing books catalog app is already implemented in Kotlin and Swift.
+* The platform-side app has existing middleware constraints that should also
+  be the middleware foundation for the additional Flutter screen.
+  * On Android, the Kotlin app already uses GSON and OkHttp for networking and
+    references the Google Books API as a data source. These same libraries also
+    underpin the data fetched and shown in the Flutter screen.
+  * On iOS, the Swift app does a similar fetch and parse of the Google Books API
+    using iOS's built-in libraries.
+* The platform application interfaces with the Flutter book details page using
+  idiomatic platform API conventions rather than Flutter conventions.
+  * On Android, the Flutter activity receives the book to show via activity
+    intent and returns the edited book by setting the result intent on the
+    activity. No Flutter concepts are leaked into the consumer activity.
+  * On iOS, Storyboards are used to design the presentation of the books, just
+    as one might do in a full UIKit app.
+* The [pigeon](https://pub.dev/packages/pigeon) plugin is used to generate
+  interop APIs and data classes. The same `Book` model class is used within the
+  Kotlin/Swift program, the Dart program and in the interop between Kotlin/Swift
+  and Dart. No manual platform channel plumbing needed for interop.
+  * The `api.dart/java/mm` files generated from the
+    `flutter_module_books/pigeon/schema.dart` file are checked into source
+    control. Therefore `pigeon` is only a dev dependency with no runtime
+    requirements.
+  * If the `schema.dart` is modified, the generated classes can be updated with
+
+      ```bash
+      dart run pigeon --input pigeon/schema.dart \
+        --dart_out lib/api.dart \
+        --objc_header_out ../ios_books/IosBooks/api.h \
+        --objc_source_out ../ios_books/IosBooks/api.m \
+        --objc_prefix BK \
+        --java_out ../android_books/app/src/main/java/dev/flutter/example/books/Api.java \
+        --java_package "dev.flutter.example.books"
+      ```
+
+      in the `flutter_module_books` directory.
+
+Once you've understood the basics of add-to-app with `android_fullscreen` and
+`ios_fullscreen`, this is a good sample to demonstrate how to integrate Flutter
+in a slightly more realistic setting with existing business logic.
+
+## tl;dr
+
+If you're just looking to get up and running quickly, these bash commands will
+fetch packages and set up dependencies (note that the above commands assume
+you're building for both iOS and Android, with both toolchains installed):
+
+```bash
+  #!/bin/bash
+  set -e
+
+  cd flutter_module_books/
+  flutter pub get
+
+  # For Android builds:
+  open -a "Android Studio" ../android_books # macOS only
+  # Or open the ../android_books folder in Android Studio for other platforms.
+
+  # For iOS builds:
+  cd ../ios_books
+  pod install
+  open IosBooks.xcworkspace
+```
+
+## Requirements
+
+* Flutter
+* Android Studio
+* Cocoapods (iOS)
+
+## Questions/issues
+
+See [add_to_app/README.md](../README.md) for further help.
