【中文标题】带有圆角的 Flutter WebView【英文标题】:Flutter WebView With Rounded Corners 【发布时间】:2019-10-21 07:49:06 【问题描述】:容器( 约束:BoxConstraints(最大高度:300,), 装饰:盒子装饰( 边界半径:边界半径.all(半径.圆形(20)), ), 孩子:网络视图( initialUrl: 'https://flutter.io', ) ),
【问题讨论】:
【参考方案1】:你可以使用 ClipRRect,我添加黄色来增强这个演示的效果 你可以看到下面的图片 代码sn-p
Container(
color: Colors.yellow,
constraints: BoxConstraints(maxHeight: 300),
child: ClipRRect(
borderRadius: BorderRadius.all(
const Radius.circular(20.0),
),
child: WebView(
initialUrl: "https://flutter.io"
),
),
)
完整代码
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget
// This widget is the root of your application.
@override
Widget build(BuildContext context)
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
// This is the theme of your application.
//
// Try running your application with "flutter run". You'll see the
// application has a blue toolbar. Then, without quitting the app, try
// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).
// Notice that the counter didn't reset back to zero; the application
// is not restarted.
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
class MyHomePage extends StatefulWidget
MyHomePage(Key key, this.title) : super(key: key);
// This widget is the home page of your application. It is stateful, meaning
// that it has a State object (defined below) that contains fields that affect
// how it looks.
// This class is the configuration for the state. It holds the values (in this
// case the title) provided by the parent (in this case the App widget) and
// used by the build method of the State. Fields in a Widget subclass are
// always marked "final".
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
class _MyHomePageState extends State<MyHomePage>
int _counter = 0;
void _incrementCounter()
setState(()
// This call to setState tells the Flutter framework that something has
// changed in this State, which causes it to rerun the build method below
// so that the display can reflect the updated values. If we changed
// _counter without calling setState(), then the build method would not be
// called again, and so nothing would appear to happen.
_counter++;
);
@override
Widget build(BuildContext context)
// This method is rerun every time setState is called, for instance as done
// by the _incrementCounter method above.
//
// The Flutter framework has been optimized to make rerunning build methods
// fast, so that you can just rebuild anything that needs updating rather
// than having to individually change instances of widgets.
return Scaffold(
appBar: AppBar(
// Here we take the value from the MyHomePage object that was created by
// the App.build method, and use it to set our appbar title.
title: Text(widget.title),
),
body: Container(
color: Colors.yellow,
constraints: BoxConstraints(maxHeight: 300),
child: ClipRRect(
borderRadius: BorderRadius.all(
const Radius.circular(20.0),

child: WebView(
initialUrl: "https://flutter.io"
),

),
floatingActionButton: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: Icon(Icons.add),
), // This trailing comma makes auto-formatting nicer for build methods.
