1.原生的android代碼跳轉Flutter頁面有黑屏的情況，

跳轉方式如下：

        // 實例化FlutterEngine對象
        FlutterEngine flutterEngine = new FlutterEngine(this);
        // 設置初始路由
        flutterEngine.getNavigationChannel().setInitialRoute("route1");
        // 開始執(zhí)行dart代碼來pre-warm FlutterEngine
        flutterEngine.getDartExecutor().executeDartEntrypoint(
                DartExecutor.DartEntrypoint.createDefault()
        );
        // 緩存FlutterEngine
        FlutterEngineCache.getInstance().put("my_engine_id", flutterEngine);
        //跳轉到Flutter頁面有黑屏現(xiàn)象
        Intent intent = FlutterActivity.withCachedEngine("my_engine_id").build(MainActivity.this);
        startActivity(intent);

在Android響應Activity對應的theme中添加如下

<item name="android:background">@android:color/transparent</item>

2.原生android接入flutter遇到的一個編譯問題，

在android原生項目中創(chuàng)建Flutter的module，在編譯時遇到

FAILURE: Build failed with an exception.

* Where:
Script 'D:\fluttersdk\packages\flutter_tools\gradle\flutter.gradle' line: 752

* What went wrong:
A problem occurred configuring project ':app'.
> Failed to notify project evaluation listener.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.
   > Could not get unknown property 'android' for project ':app' of type org.gradle.api.Project.

解決編譯問題:
android原生項目中的app目錄被我改成了app-platform,在x:\fluttersdk\packages\flutter_tools\gradle\flutter.gradle' line: 752處附近，找到

            // Flutter module included as a subproject in add to app.
            String hostAppProjectName = project.rootProject.hasProperty('flutter.hostAppProjectName') ? project.rootProject.property('flutter.hostAppProjectName')  : "app"
            Project appProject = project.rootProject.findProject(":${hostAppProjectName}")
            assert appProject != null : "Project :${hostAppProjectName} doesn't exist. To custom the host app project name, set `org.gradle.project.flutter.hostAppProjectName=<project-name>` in gradle.properties."

將"app"改成"app-platform",重新編譯，只能解決編譯問題哦。
