FlutterBoost #

A next-generation Flutter-Native hybrid solution. FlutterBoost is a Flutter plugin which enables hybrid integration of Flutter for your existing native apps with minimum efforts.The philosophy of FlutterBoost is to use Flutter as easy as using a WebView. Managing Native pages and Flutter pages at the same time is non-trivial in an existing App. FlutterBoost takes care of page resolution for you. The only thing you need to care about is the name of the page(usually could be an URL). 

Prerequisites #

You need to add Flutter to your project before moving on.The version of the flutter SDK requires v1.9.1+hotfixes, or it will compile error.

Getting Started #

Add a dependency in you Flutter project. #

Open you pubspec.yaml and add the following line to dependencies:

androidx branch

        url: 'https://github.com/alibaba/flutter_boost.git'
        ref: ' 1.12.13'

support branch

        url: 'https://github.com/alibaba/flutter_boost.git'
        ref: 'task/task_v1.12.13_support_hotfixes'

A better implementation to support Flutter v1.9.1+hotfixes

Change the content android:

  1. based on the v1.9.1+hotfixes branch of flutter
  2. Solve major bugs, such as page parameter passing
  3. Support platformview
  4. Support androidx branch :feature/flutter_1.9_androidx_upgrade
  5. Resolve memory leaks
  6. Rewrite part of the code
  7. API changes
  8. Improved demo and added many demo cases


1.based on the v1.9.1+hotfixes branch of flutter 2.bugfixed

0.1.5 #

The main changes are as following:

  1. The new version do the page jump (URL route) based on the inherited FlutterViewController or Activity. The jump procedure will create new instance of FlutterView, while the old version just reuse the underlying FlutterView
  2. Avoiding keeping and reusing the FlutterView, there is no screenshot and complex attach&detach logical any more. As a result, memory is saved and black or white-screen issue occured in old version all are solved.
  3. This version also solved the app life cycle observation issue, we recommend you to use ContainerLifeCycle observer to listen the app enter background or foreground notification instead of WidgetBinding.
  4. We did some code refactoring, the main logic became more straightforward.

0.0.1 #

  • TODO: Describe initial release.

API changes #

From the point of API changes, we did some refactoring as following:

iOS API changes

  1. FlutterBoostPlugin's startFlutterWithPlatform function change its parameter from FlutterViewController to Engine

Before change

- (void)startFlutterWithPlatform:(id<FLBPlatform>)platform onStart:(void (^)(FlutterViewController *))callback;

After change

- (void)startFlutterWithPlatform:(id<FLB2Platform>)platform
                         onStart:(void (^)(id<FlutterBinaryMessenger,
                                           FlutterPluginRegistry> engine))callback;

  1. FLBPlatform protocol removed flutterCanPop、accessibilityEnable and added entryForDart Before change:
@protocol FLBPlatform <NSObject>
//Whether to enable accessibility support. Default value is Yes.
- (BOOL)accessibilityEnable;
// flutter模块是否还可以pop
- (void)flutterCanPop:(BOOL)canpop;
- (void)openPage:(NSString *)name
          params:(NSDictionary *)params
      completion:(void (^)(BOOL finished))completion;
- (void)closePage:(NSString *)uid
           params:(NSDictionary *)params
       completion:(void (^)(BOOL finished))completion;

After change:

@protocol FLB2Platform <NSObject>
- (NSString *)entryForDart;
- (void)open:(NSString *)url
   urlParams:(NSDictionary *)urlParams
        exts:(NSDictionary *)exts
      completion:(void (^)(BOOL finished))completion;
- (void)close:(NSString *)uid
       result:(NSDictionary *)result
         exts:(NSDictionary *)exts
   completion:(void (^)(BOOL finished))completion;

Android API changes

Android mainly changed the IPlatform interface and its implementation. It removed following APIs:

Activity getMainActivity();
boolean startActivity(Context context,String url,int requestCode);
Map getSettings();

And added following APIs:

void registerPlugins(PluginRegistry registry) 方法
void openContainer(Context context,String url,Map<String,Object> urlParams,int requestCode,Map<String,Object> exts);
void closeContainer(IContainerRecord record, Map<String,Object> result, Map<String,Object> exts);
IFlutterEngineProvider engineProvider();
int whenEngineStart();


import 'package:flutter/material.dart';
import 'package:flutter_boost/flutter_boost.dart';
import 'simple_page_widgets.dart';

void main() {

class MyApp extends StatefulWidget {
  _MyAppState createState() => _MyAppState();

class _MyAppState extends State<MyApp> {
  void initState() {

      'embeded': (pageName, params, _)=>EmbededFirstRouteWidget(),
      'first': (pageName, params, _) => FirstRouteWidget(),
      'second': (pageName, params, _) => SecondRouteWidget(),
      'tab': (pageName, params, _) => TabRouteWidget(),
      'platformView': (pageName, params, _) => PlatformRouteWidget(),
      'flutterFragment': (pageName, params, _) => FragmentRouteWidget(params),
      ///可以在native层通过 getContainerParams 来传递参数
      'flutterPage': (pageName, params, _) {
        print("flutterPage params:$params");

        return FlutterRouteWidget(params:params);

  Widget build(BuildContext context) {
    return MaterialApp(
        title: 'Flutter Boost example',
        builder: FlutterBoost.init(postPush: _onRoutePushed),
        home: Container(

  void _onRoutePushed(
      String pageName, String uniqueId, Map params, Route route, Future _) {
class TestBoostNavigatorObserver extends NavigatorObserver{
  void didPush(Route<dynamic> route, Route<dynamic> previousRoute) {


  void didPop(Route<dynamic> route, Route<dynamic> previousRoute) {

  void didRemove(Route<dynamic> route, Route<dynamic> previousRoute) {

  void didReplace({Route<dynamic> newRoute, Route<dynamic> oldRoute}) {
