在我的代码，当我试图按下按钮“采取截图和共享”在iOS -我成功地可以保存和共享截图。但是在android中我得到下一个错误：

我尝试在主文件夹中添加androidManifest的权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

但对我没用我不确定是否是权限的问题，或者我指定了错误的权限...但如果同样的代码没有在iPhone中导致错误，那么也许它真的在它们中？
这是完整的代码：

import 'dart:io';

import 'package:flutter/material.dart';
import 'package:path_provider/path_provider.dart';
import 'package:screenshot/screenshot.dart';
import 'package:share/share.dart';

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

class MyApp extends StatefulWidget {
  @override
  State<StatefulWidget> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final _screenshotController = ScreenshotController();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home: Scaffold(
            body: Center(
                child: Column(
                    mainAxisAlignment: MainAxisAlignment.center,
                    children: [
          Screenshot(
            controller: _screenshotController,
            child: Card(
                child: Padding(
              padding: EdgeInsets.all(16),
              child: Column(
                children: [
                  Image.asset('assets/images/customerPhotos.png'),
                  Text(
                    'Code Passionately',
                    style: TextStyle(fontSize: 30, fontWeight: FontWeight.bold),
                  ),
                ],
              ),
            )),
          ),
          TextButton(
            child: Text('Take Screenshot and Share'),
            onPressed: _takeScreenshot,
          )
        ]))));
  }

  void _takeScreenshot() async {
    final uint8List = await _screenshotController.capture();
    String tempPath = (await getTemporaryDirectory()).path;
    File file = File('$tempPath/customerPhotos.png');
    await file.writeAsBytes(uint8List as List<int>);
    await Share.shareFiles([file.path]);
  }
}

我改变lib 'share' which 'share_plus'，现在共享工作：

import 'dart:io';
import 'package:file_selector/file_selector.dart';
import 'package:flutter/material.dart';
import 'package:path_provider/path_provider.dart';
import 'package:screenshot/screenshot.dart';
import 'package:share_plus/share_plus.dart';

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

class MyApp extends StatefulWidget {
  @override
  State<StatefulWidget> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final _screenshotController = ScreenshotController();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home: Scaffold(
            body: Center(
                child: Column(
                    mainAxisAlignment: MainAxisAlignment.center,
                    children: [
          Screenshot(
            controller: _screenshotController,
            child: Card(
                child: Padding(
              padding: EdgeInsets.all(16),
              child: Column(
                children: [
                  Image.asset('assets/images/customerPhotos.png'),
                  Text(
                    'Code Passionately',
                    style: TextStyle(fontSize: 30, fontWeight: FontWeight.bold),
                  ),
                ],
              ),
            )),
          ),
          TextButton(
            child: Text('Take Screenshot and Share'),
            onPressed: _takeScreenshot,
          )
        ]))));
  }

  void _takeScreenshot() async {
    final uint8List = await _screenshotController.capture();
    String tempPath = (await getTemporaryDirectory()).path;
    File file = File('$tempPath/customerPhotos.png');
    await file.writeAsBytes(uint8List as List<int>);
    final xFile = XFile(file.path);
    await Share.shareXFiles([xFile]);
  }
}

但现在我有了另一个问题：在Android中，我无法选择save into galary选项。如何添加此？enter image description here
