更新(Android >= 11):

iOS configuration: Open info.plist file and add: <key>LSApplicationQueriesSchemes</key> <array> <string>https</string> </array> Android configuration: Open AndroidManifest.xml file located in app/src/main and add the following at the root: <manifest xmlns:android="http://schemas.android.com/apk/res/android"> <!-- Add this query --> <queries> <intent> <action android:name="android.intent.action.VIEW" /> <data android:scheme="https" /> </intent> </queries> <application ... /> </manifest>

颤振代码:

简单地包装你的文本在一个手势探测器或InkWell和处理点击在onTap()使用url_launcher包。

InkWell(
  onTap: () => launchUrl(Uri.parse('https://www.google.com')),
  child: Text(
    'Click here',
    style: TextStyle(decoration: TextDecoration.underline, color: Colors.blue),
  ),
)

可以使用flutter_linkify包 https://pub.dev/packages/flutter_linkify 只是想提供另一种选择。 包会自动划分文本并突出显示http/https 结合插件url_launcher你可以启动url 你可以查看下面的例子:

完整代码如下

import 'package:flutter/material.dart';
import 'package:flutter_linkify/flutter_linkify.dart';
import 'dart:async';

import 'package:url_launcher/url_launcher.dart';

void main() => runApp(new LinkifyExample());

class LinkifyExample extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'flutter_linkify example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('flutter_linkify example'),
        ),
        body: Center(
          child: Linkify(
            onOpen: _onOpen,
            text: "Made by https://cretezy.com \n\nMail: example@gmail.com \n\n  this is test http://pub.dev/ ",
          ),
        ),
      ),
    );
  }

  Future<void> _onOpen(LinkableElement link) async {
    if (await canLaunch(link.url)) {
      await launch(link.url);
    } else {
      throw 'Could not launch $link';
    }
  }
}

你可以使用链接文本https://pub.dev/packages/link_text 然后像这样使用它

 final String _text = 'Lorem ipsum https://flutter.dev\nhttps://pub.dev'; 
 @override
 Widget build(BuildContext context) {
 return Scaffold(
     body: Center(
      child: LinkText(
        text: _text,
        textAlign: TextAlign.center,
      ),
    ),
  );
}

在你的应用中添加可点击链接的另一种(或不是)方式(对我来说就是这样):

1 -在你的pubspec中添加url_launcher包。yaml文件

(包版本5.0对我来说不太好，所以我使用4.2.0+3)。

dependencies:
  flutter:
    sdk: flutter
  url_launcher: ^4.2.0+3

2 -导入并使用如下。

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

void main() {
  runApp(MaterialApp(
    title: 'Navigation Basics',
    home: MyUrl(),
  ));
}

class MyUrl extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Url Launcher'),
      ),
      body: Center(
        child: FlatButton(
          onPressed: _launchURL,
          child: Text('Launch Google!',
              style: TextStyle(fontSize: 17.0)),
        ),
      ),
    );
  }

  _launchURL() async {
    const url = 'https://google.com.br';
    if (await canLaunch(url)) {
      await launch(url);
    } else {
      throw 'Could not launch $url';
    }
  }
}

Flutter没有内置的超链接支持，但您可以自己伪造它。画廊的抽屉里有个例子，飞镖。他们使用一个RichText小部件包含一个彩色的TextSpan，它有一个识别器属性来处理点击:

        RichText(
          text: TextSpan(
            children: [
              TextSpan(
                style: bodyTextStyle,
                text: seeSourceFirst,
              ),
              TextSpan(
                style: bodyTextStyle.copyWith(
                  color: colorScheme.primary,
                ),
                text: repoText,
                recognizer: TapGestureRecognizer()
                  ..onTap = () async {
                    final url = 'https://github.com/flutter/gallery/';
                    if (await canLaunch(url)) {
                      await launch(
                        url,
                        forceSafariVC: false,
                      );
                    }
                  },
              ),
              TextSpan(
                style: bodyTextStyle,
                text: seeSourceSecond,
              ),
            ],
          ),

在Flutter 2.0中，引入了Link小部件。使用这个小部件来启动网页，也可以导航到应用程序中的新屏幕。在使用它之前，你需要使用url_launcher包。

url_launcher: ^6.0.8
