base on A collection of Flutter examples and demos # Flutter samples [](https://github.com/flutter/samples/actions?workflow=Main%20Branch%20CI) A collection of open source samples that illustrate best practices for [Flutter]. ## Index ### Quickstarts * [`asset_transformation`] - Demonstrates how to transform images' color scales and formats. * [`background_isolate_channels`] - Demonstrates how to use long-lived isolates. * [`code_sharing`] - Demonstrates how to share business logic between Flutter client and Dart server using [`package:shelf`] ) * [`context_menus`] - This sample shows how to create and customize cross-platform context menus, such as the text selection toolbar on mobile or the right click menu on desktop. * [`desktop_photo_search`] - Demonstrates desktop features in both Material and FluentUI design systems. * [`dynamic_theme`] - A developer sample demonstrating how to call on-device Flutter APIs based on output from the Gemini API. * [`form_app`] - A sample demonstrating different types of forms and best practices. * [`game_template`] - (**note: deprecated!**) A starter game in Flutter with all the bells and whistles of a mobile (iOS & Android) game. * [`gemini_tasks`] - A developer sample written in Flutter demonstrating how to interact with a to-do list in natural language using the Gemini API. * [`google_maps`] - Demonstrates the Google Maps for Flutter plugin. * [`infinite_list`] - A Flutter sample app that shows an implementation of the "infinite list" UX pattern. * [`isolate_example`] - A sample application that demonstrate best practices when using [isolates]. * [`navigation_and_routing`] - A sample that shows how to use [go_router] API to handle common navigation scenarios. * [`place_tracker`] - A sample place tracking app that uses the [google_maps_flutter plugin]. * [`platform_design`] - This sample project shows a Flutter app that maximizes application code reuse while adhering to different design patterns on Android and iOS. * [`provider_counter`] - The starter Flutter application, but using [package:provider] to manage state. * [`provider_shopper`] - A Flutter sample app that shows a state management approach using [package:provider]. * [`simple_shader`] - A simple [Flutter fragment shaders] sample project. * [`simplistic_calculator`] - A calculator to demonstrate a simple start for a desktop Flutter app. * [`simplistic_editor`] - This sample text editor showcases the use of [TextEditingDeltas] and a DeltaTextInputClient to expand and contract styled ranges of text. * [`testing_app`] - A sample app that shows different types of testing in Flutter. * [`web_embedding`] - This directory contains examples of how to embed Flutter in web apps (without iframes). * [`element_embedding_demo`] - Modifies the index.html of a flutter app so it is launched in a custom hostElement. This is the most basic embedding example. * [`ng-flutter`] - A simple Angular app (and component) that replicates the above example, but in an Angular style. ### Native platform samples * [`add-to-app`] - Collection of samples that demonstrate embedding Flutter a view into a native app. * [`fullscreen`] — Embeds a full screen instance of Flutter into an existing iOS or Android app. * [`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`] — Embeds a full screen Flutter instance that is using plugins into an existing iOS or Android app. * [`books`] — Mimics a real world use-case of embedding Flutter into an existing Android app and demonstrates using [Pigeon] to communicate between Flutter and the host application. * [`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`] — Shows how to integrate a Flutter add-to-app module at a view level for Android. * [`android_splash_screen`] * [`ios_app_clip`] * [`platform_channels`] - A sample app which demonstrates how to use MethodChannel, EventChannel, BasicMessageChannel and MessageCodec in Flutter. * [`platform_view_swift`] - A Flutter sample app that combines a native iOS UIViewController with a full-screen Flutter view. ### Demo galleries * [`animations`] - Showcases Flutter's animation features * [`material_3_demo`] - showcases [Material 3] features in the Flutter Material library. ### Demo apps * [`compass_app`] - A sample application that implements MVVM architecture. * [`deeplink_store_example`] - A demo app that implements deep-linking with go_router. * [`veggie_seasons`] - A demo application. ## Flutter sample code Samples are **correct and concise code** that developers can **quickly understand** and **easily reuse** with minimal side effects. Samples teach developers how to be successful using Flutter and Dart. They are maintained on an ongoing basis to reflect changing APIs and best practices. ### Types of samples There are two types of sample code in this repository: * **Quickstarts** provide a starting point to extend. They answer the question, "What is the minimal amount of code needed to implement this feature?" * **Demo apps** are meant to be built and ran. They demo the _product_, not how to write code. A majority of samples in this repository are quickstarts. ## Usage Every sample in this repo is fully runnable. To run an example, use `flutter run` inside that example's directory. See the [getting started guide] to install the `flutter` tool. > [!IMPORTANT] > If you want to run an add-to-app sample, there are additional requirements. > We suggest reading the [add-to-app documentation]. ### Tip: minimize download size As this repository is quite big, you can use [svn] to download a single example. For example: ``` svn co https://github.com/flutter/samples/trunk/provider_shopper ``` You can also use a [partial clone] to skip blob objects that aren't currently checked out, while including the full commit history: ``` git clone --filter=blob:none https://github.com/flutter/samples.git ``` ## Interested in contributing? See the [contributor's guide]! ## Questions or issues? If you have a general question about one of these samples or how to adapt its techniques for one of your own apps, try one of these resources: * [The FlutterDev Discord] * [The Flutter Community forum] If you run into a bug in one of the samples, please file an issue in the [`flutter/samples` issue tracker].
