`nfc_manager` 需要`permission_handler` 的什么许可？

Question

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)
    • macOS (desktop)   • macos      • darwin-x64     • macOS 11.4 20F71 darwin-x64
    • Chrome (web)      • chrome     • web-javascript • Google Chrome 91.0.4472.101

• No issues found!

如果我运行

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'));
            },
          ),
        ),
      ),
    );

我得到输出

我想避免经历手动添加权限的过程
bu 我不确定我应该请求 permission_handler 的哪个许可
访问 NFC

你能帮忙吗？

Answer 1

你不需要permission_handler插件来请求权限android.permission.NFC因为它是正常权限，而不是危险允许。只需在AndroidManifest.xml声明即可，无需权限处理
