如何进入全屏模式

Question

我使用setEnabledSystemUIOverlays隐藏状态栏和虚拟按钮栏。

但屏幕顶部和底部有空白（如图所示）：

有谁知道如何解决它？

这是我的代码：

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() {
  SystemChrome.setEnabledSystemUIOverlays([]);
  runApp(new MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: "Test",
      home: new MyHomePage(title: "Test"),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final String title;

  MyHomePage({Key key, this.title}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text(title),
      ),
      body: new Container(
        color: Colors.red,
      ),
    );
  }
}

Answer 1

Android上似乎有an issue。由于某些原因，它不会重新计算SafeArea。

Answer 2

这对我来说很完美：

  @override
  Widget build(BuildContext context) {

    // To make this screen full screen.
    // It will hide status bar and notch.
    SystemChrome.setEnabledSystemUIOverlays([]);

    // full screen image for splash screen.
    return Container(
            child: new Image.asset('assets/splash.png', fit: BoxFit.fill));
      }
    }

导入此

import 'package:flutter/services.dart';

Answer 3

设置resizeToAvoidBottomPadding：对Scaffold为false。

   return Scaffold(
      resizeToAvoidBottomPadding: false,
   );

Answer 4

颤动 2.x：

• 仍然有这个问题。
• // resizeToAvoidBottomInset: false 不适合我。

我的解决方案：

• Container.height = Get.height // 设置 max height
• Container.child.image.fit = BoxFit.fill // 用这个
• 这对我有用，在 flutter 2.2.0
下

  final SplashController c = Get.find();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        /// key! fix full screen
        height: Get.height,

        ///
        child: Lottie.asset(
          /// image file:
          AppConfig.splash1,

          /// key! fix full screen
          fit: BoxFit.fill,

          ///

          frameRate: FrameRate(60),
          repeat: true,

          ///
          delegates: LottieDelegates(
            text: (initialText) => 'test',
          ),

          onLoaded: (composition) {
            c.animationController..duration = composition.duration;
          },
        ),
      ),

      /// not work
      // resizeToAvoidBottomInset: false,
      backgroundColor: Colors.white,
    );
  }
