Flutter 碎知识(一) 设置启动页

作者:互联网

一、在main入口配置

void main() async{
  // SystemChrome.setEnabledSystemUIOverlays([]);//隐藏状态栏,底部按钮栏
  // SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.bottom]);//隐藏状态栏,保留底部按钮栏
  // SystemChrome.setEnabledSystemUIOverlays(SystemUiOverlay.values);//显示状态栏、底部按钮栏

  SystemChrome.setSystemUIOverlayStyle(const SystemUiOverlayStyle( //设置状态栏透明
    statusBarColor: Colors.transparent,
    statusBarIconBrightness: Brightness.dark,
  ));

  WidgetsBinding widgetsBinding = WidgetsFlutterBinding.ensureInitialized();//设置启动页
  FlutterNativeSplash.preserve(widgetsBinding: widgetsBinding);

  await SystemChrome.setPreferredOrientations([ DeviceOrientation.portraitUp] );
  runApp(const MyApp());
}

二、在 项目名\android\app\src\main\res\drawable\launch_background.xml地址配置

<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!--     <item android:drawable="@android:color/white" />-->
    <item>
        <bitmap android:gravity="fill" android:src="@drawable/background"/>
    </item>
    <!-- You can insert your own image assets here 自己项目的图片 -->
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/splash" />
    </item>
</layer-list>
