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

Question

I'm using the plugins below

  nfc_manager: ^3.1.0
  permission_handler: ^8.1.0

with this setup

[✓] Flutter (Channel stable, 2.2.2, on macOS 11.4 20F71 darwin-x64, locale en-EE)
...
[✓] Connected device (3 available)

if I run

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

I get the output

I/flutter (22369): Permission.camera

I/flutter (22369): Permission.appTrackingTransparency
I/flutter (22369): Permission.criticalAlerts
I/flutter (22369): Permission.accessNotificationPolicy

I'd like to avoid to go through the process of manually adding the permissions
bu I'm not sure which permission from permission_handler should I request
to access NFC

can you help?

You don't need permission_handler plugin to request permission android.permission.NFC because it's normal permission, not dangerous permission. Simply declare it in AndroidManifest.xml , no permission handling is required.
