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:

support branch

flutter_boost:
    git:
        url: 'https://github.com/alibaba/flutter_boost.git'
        ref: '0.1.61'

androidx branch

flutter_boost:
    git:
        url: 'https://github.com/alibaba/flutter_boost.git'
        ref: 'feature/flutter_1.9_androidx_upgrade'

Integration with Flutter code.

Add init code to you App

void main() {
    runApp(MyApp());
}

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

class _MyAppState extends State<MyApp> {
    @override
    void initState() {
    super.initState();
    
        FlutterBoost.singleton.registerPageBuilders({
            'first': (pageName, params, _) => FirstRouteWidget(),
            'second': (pageName, params, _) => SecondRouteWidget(),
            'tab': (pageName, params, _) => TabRouteWidget(),
            'platformView': (pageName, params, _) => PlatformRouteWidget(),
            'flutterFragment': (pageName, params, _) => FragmentRouteWidget(params),
            'flutterPage': (pageName, params, _) {
                print("flutterPage params:$params");
            
                return FlutterRouteWidget(params:params);
            },
        });
    }
    
    @override
    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 _) {
    }
}

Integration with iOS code.

Note: You need to add libc++ into "Linked Frameworks and Libraries"

objective-c:

Use FLBFlutterAppDelegate as the superclass of your AppDelegate

@interface AppDelegate : FLBFlutterAppDelegate <UIApplicationDelegate>
@end

Implement FLBPlatform protocol methods for your App.

@interface PlatformRouterImp : NSObject<FLBPlatform>
@property (nonatomic,strong) UINavigationController *navigationController;
@end


@implementation PlatformRouterImp

#pragma mark - Boost 1.5
- (void)open:(NSString *)name
   urlParams:(NSDictionary *)params
        exts:(NSDictionary *)exts
  completion:(void (^)(BOOL))completion
{
    BOOL animated = [exts[@"animated"] boolValue];
    FLBFlutterViewContainer *vc = FLBFlutterViewContainer.new;
    [vc setName:name params:params];
    [self.navigationController pushViewController:vc animated:animated];
    if(completion) completion(YES);
}

- (void)present:(NSString *)name
   urlParams:(NSDictionary *)params
        exts:(NSDictionary *)exts
  completion:(void (^)(BOOL))completion
{
    BOOL animated = [exts[@"animated"] boolValue];
    FLBFlutterViewContainer *vc = FLBFlutterViewContainer.new;
    [vc setName:name params:params];
    [self.navigationController presentViewController:vc animated:animated completion:^{
        if(completion) completion(YES);
    }];
}

- (void)close:(NSString *)uid
       result:(NSDictionary *)result
         exts:(NSDictionary *)exts
   completion:(void (^)(BOOL))completion
{
    BOOL animated = [exts[@"animated"] boolValue];
    animated = YES;
    FLBFlutterViewContainer *vc = (id)self.navigationController.presentedViewController;
    if([vc isKindOfClass:FLBFlutterViewContainer.class] && [vc.uniqueIDString isEqual: uid]){
        [vc dismissViewControllerAnimated:animated completion:^{}];
    }else{
        [self.navigationController popViewControllerAnimated:animated];
    }
}
@end

Initialize FlutterBoost with FLBPlatform at the beginning of your App, such as AppDelegate.

    PlatformRouterImp *router = [PlatformRouterImp new];
    [FlutterBoostPlugin.sharedInstance startFlutterWithPlatform:router
                                                        onStart:^(FlutterEngine *engine) {
                                                            
                                                        }];

swift:

init

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
  ) -> Bool {
    
    let router = PlatformRouterImp.init();
    FlutterBoostPlugin.sharedInstance()?.startFlutter(with: router, onStart: { (engine) in
    });
    
    self.window = UIWindow.init(frame: UIScreen.main.bounds)
    let viewController = ViewController.init()
    let navi = UINavigationController.init(rootViewController: viewController)
    self.window.rootViewController = navi
    self.window.makeKeyAndVisible()
    
    return true;//super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Implement FLBPlatform protocol methods for your App.

class PlatformRouterImp: NSObject, FLBPlatform {
    func open(_ url: String, urlParams: [AnyHashable : Any], exts: [AnyHashable : Any], completion: @escaping (Bool) -> Void) {
        var animated = false;
        if exts["animated"] != nil{
            animated = exts["animated"] as! Bool;
        }
        let vc = FLBFlutterViewContainer.init();
        vc.setName(url, params: urlParams);
        self.navigationController().pushViewController(vc, animated: animated);
        completion(true);
    }
    
    func present(_ url: String, urlParams: [AnyHashable : Any], exts: [AnyHashable : Any], completion: @escaping (Bool) -> Void) {
        var animated = false;
        if exts["animated"] != nil{
            animated = exts["animated"] as! Bool;
        }
        let vc = FLBFlutterViewContainer.init();
        vc.setName(url, params: urlParams);
        navigationController().present(vc, animated: animated) {
            completion(true);
        };
    }
    
    func close(_ uid: String, result: [AnyHashable : Any], exts: [AnyHashable : Any], completion: @escaping (Bool) -> Void) {
        var animated = false;
        if exts["animated"] != nil{
            animated = exts["animated"] as! Bool;
        }
        let presentedVC = self.navigationController().presentedViewController;
        let vc = presentedVC as? FLBFlutterViewContainer;
        if vc?.uniqueIDString() == uid {
            vc?.dismiss(animated: animated, completion: {
                completion(true);
            });
        }else{
            self.navigationController().popViewController(animated: animated);
        }
    }
    
    func navigationController() -> UINavigationController {
        let delegate = UIApplication.shared.delegate as! AppDelegate
        let navigationController = delegate.window?.rootViewController as! UINavigationController
        return navigationController;
    }
}

Integration with Android code.

Init FlutterBoost in Application.onCreate()

public class MyApplication extends Application {


    @Override
    public void onCreate() {
        super.onCreate();
        INativeRouter router =new INativeRouter() {
            @Override
            public void openContainer(Context context, String url, Map<String, Object> urlParams, int requestCode, Map<String, Object> exts) {
               String  assembleUrl=Utils.assembleUrl(url,urlParams);
                PageRouter.openPageByUrl(context,assembleUrl, urlParams);
            }

        };

        FlutterBoost.BoostLifecycleListener lifecycleListener= new FlutterBoost.BoostLifecycleListener() {
            @Override
            public void onEngineCreated() {

            }

            @Override
            public void onPluginsRegistered() {
                MethodChannel mMethodChannel = new MethodChannel( FlutterBoost.instance().engineProvider().getDartExecutor(), "methodChannel");
                Log.e("MyApplication","MethodChannel create");
                TextPlatformViewPlugin.register(FlutterBoost.instance().getPluginRegistry().registrarFor("TextPlatformViewPlugin"));

            }

            @Override
            public void onEngineDestroy() {

            }
        };
        Platform platform= new FlutterBoost
                .ConfigBuilder(this,router)
                .isDebug(true)
                .whenEngineStart(FlutterBoost.ConfigBuilder.ANY_ACTIVITY_CREATED)
                .renderMode(FlutterView.RenderMode.texture)
                .lifecycleListener(lifecycleListener)
                .build();

        FlutterBoost.instance().init(platform);



    }
}

Basic Usage

Concepts

All page routing requests are being sent to the native router. Native router communicates with Native Container Manager, Native Container Manager takes care of building and destroying of Native Containers.

Use Flutter Boost Native Container to show a Flutter page in native code.

iOS

 FLBFlutterViewContainer *vc = FLBFlutterViewContainer.new;
        [vc setName:name params:params];
        [self.navigationController presentViewController:vc animated:animated completion:^{}];

However, in this way, you cannot get the page data result after the page finished. We suggest you implement the platform page router like the way mentioned above. And finally open/close the VC as following:

//push the page
[FlutterBoostPlugin open:@"first" urlParams:@{kPageCallBackId:@"MycallbackId#1"} exts:@{@"animated":@(YES)} onPageFinished:^(NSDictionary *result) {
        NSLog(@"call me when page finished, and your result is:%@", result);
    } completion:^(BOOL f) {
        NSLog(@"page is opened");
    }];
//prsent the page
[FlutterBoostPlugin open:@"second" urlParams:@{@"present":@(YES),kPageCallBackId:@"MycallbackId#2"} exts:@{@"animated":@(YES)} onPageFinished:^(NSDictionary *result) {
        NSLog(@"call me when page finished, and your result is:%@", result);
    } completion:^(BOOL f) {
        NSLog(@"page is presented");
    }];
//close the page
[FlutterBoostPlugin close:yourUniqueId result:yourdata exts:exts completion:nil];

Android

public class PageRouter {

    public final static Map<String, String> pageName = new HashMap<String, String>() {{


        put("first", "first");
        put("second", "second");
        put("tab", "tab");

        put("sample://flutterPage", "flutterPage");
    }};

    public static final String NATIVE_PAGE_URL = "sample://nativePage";
    public static final String FLUTTER_PAGE_URL = "sample://flutterPage";
    public static final String FLUTTER_FRAGMENT_PAGE_URL = "sample://flutterFragmentPage";

    public static boolean openPageByUrl(Context context, String url, Map params) {
        return openPageByUrl(context, url, params, 0);
    }

    public static boolean openPageByUrl(Context context, String url, Map params, int requestCode) {

        String path = url.split("\\?")[0];

        Log.i("openPageByUrl",path);

        try {
            if (pageName.containsKey(path)) {
                Intent intent = BoostFlutterActivity.withNewEngine().url(pageName.get(path)).params(params)
                        .backgroundMode(BoostFlutterActivity.BackgroundMode.opaque).build(context);

                context.startActivity(intent);

            } else if (url.startsWith(FLUTTER_FRAGMENT_PAGE_URL)) {
                context.startActivity(new Intent(context, FlutterFragmentPageActivity.class));
                return true;
            } else if (url.startsWith(NATIVE_PAGE_URL)) {
                context.startActivity(new Intent(context, NativePageActivity.class));
                return true;
            } else {
                return false;
            }
        } catch (Throwable t) {
            return false;
        }
        return false;
    }
}

Use Flutter Boost to open a page in dart code.

Dart

FlutterBoost.singleton
                .open("pagename")

Use Flutter Boost to close a page in dart code.

FlutterBoost.singleton.close(uniqueId);
