【问题描述】：

我正在使用下面的插件

  nfc_manager: ^3.1.0
  permission_handler: ^8.1.0

使用此设置

[✓] Flutter (Channel stable, 2.2.2, on macOS 11.4 20F71 darwin-x64, locale en-EE)
...
[✓] Connected device (3 available)
    • Pixel 3a (mobile) • 965AY0WP5C • android-arm64  • Android 11 (API 30)

    • Chrome (web)      • chrome     • web-javascript • Google Chrome 91.0.4472.101

• No issues found!

如果我跑

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

void main() => runApp(
      MaterialApp(
        home: Material(
          child: ListView.builder(
            itemCount: Permission.values.length,
            itemBuilder: (context, index) 
              final p = Permission.values[index];
              print(p);
              return Center(child: Text('$p'));
            ,
          ),
        ),
      ),
    );

我得到了输出

我想避免手动添加权限的过程 bu 我不确定我应该向permission_handler 请求哪个权限 访问 NFC

你能帮忙吗？

【参考方案1】：

您不需要permission_handler 插件来请求android.permission.NFC 权限，因为这是正常 权限，而不是危险 权限。只需在AndroidManifest.xml中声明即可，无需权限处理。

【讨论】：

android 部分我不担心，但 ios 部分真的很担心

此处提到了 iOS 设置：pub.dev/packages/nfc_manager#setup。你遵循了吗？

这正是我想要避免的
