flutter 如何获取状态栏高度

调用 MediaQuery.of(context).padding.top 即可。

import 'package:flutter/material.dart';

void main() {
  runApp(MaterialApp(
    title: 'Flutter Tutorial',
    home: TutorialHome(),
  ));
}

class TutorialHome extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // Scaffold is a layout for the major Material Components.
    return Scaffold(
      // body is the majority of the screen.
      body: Container(
        child: Column(
          children: <Widget>[
            Container(
              child: Text(
                'Hello, world!',
              ),
              // margin: EdgeInsets.only(top: 20),
              alignment: Alignment.center,
            ),
          ],
        ),
        padding: EdgeInsets.only(top: MediaQuery.of(context).padding.top),
      ),
    );
  }
}
