Flutter平台钱包管理插件platform_wallet的使用

插件简介

platform_wallet 是一个用于在iOS和Android平台上保存钱包通行证的Flutter插件。由于add_to_wallet插件在iOS上有效，但在Android上无效，因此需要创建一个简单的的插件来支持两个平台。

安装插件

安装此插件，请运行以下命令：

flutter pub add platform_wallet

使用示例

1 iOS:

final Uri uri = Uri.parse("https://example.com/pass.pkpass");
try {
  final PKPass pass = await PKPass.fromUrl(
    uri,
    headers: {"Authorization": "Bearer ..."},
  );
  pass.save();
} on PlatformWalletException catch (e) {
  print("Something went wrong...");
  print(e);
}

Android

final Uri uri = Uri.parse("https://pay.google.com/gp/v/save/ey...");  
try {
  final GooglePass pass = GooglePass.fromUrl(uri);
  pass.save();
} on PlatformWalletException catch (e) {
  print("Something went wrong...");
  print(e);
}

示例代码

import 'dart:io';

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

import 'package:platform_wallet/platform_wallet.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';

  Future<void> initPlatformState() async {
    // 初始化平台状态
    if (!mounted) return;
  }

  TextEditingController controller = TextEditingController();

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: SafeArea(
            child: FutureBuilder<bool>(
