android studio flutter 新建app 启动页黑屏的问题

 在activity 标签下 加上这段代码代码就行

 <meta-data 
android:name="io.flutter.embedding.android.SplashScreenDrawable" 
android:resource="@drawable/launch_background" /> 





完整代码如下

<activity
    android:name=".MainActivity"
    android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
    android:hardwareAccelerated="true"
    android:launchMode="singleTop"
    android:theme="@style/LaunchTheme"
    android:windowSoftInputMode="adjustResize">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    <--解决启动黑屏问题-->
    <meta-data
        android:name="io.flutter.embedding.android.SplashScreenDrawable"
        android:resource="@drawable/launch_background" />
  
</activity>
