如何在flutter中显示Oauth同意屏幕

dependencies:
  flutter_webview_plugin: ^0.4.0

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

class OauthScreen extends StatelessWidget {
  final String oauthUrl; // Oauth授权页面的URL

  OauthScreen({required this.oauthUrl});

  @override
  Widget build(BuildContext context) {
    return WebviewScaffold(
      url: oauthUrl,
      appBar: AppBar(
        title: Text('Oauth同意屏幕'),
      ),
    );
  }
}

FlatButton(
  onPressed: () {
    Navigator.push(
      context,
      MaterialPageRoute(
        builder: (context) => OauthScreen(
          oauthUrl: 'https://example.com/oauth', // 替换为你的Oauth授权页面的URL
        ),
      ),
    );
  },
  child: Text('显示Oauth同意屏幕'),
),
