如何请求用户访问手机存储空间？

在此输入图像描述

我尝试从 Youtube 编写一些画廊选择器功能，但我想请求用户的存储许可，当我在下面编写代码时，我会进入应用程序信息，为什么我会到达那里以及如何修复它

import 'package:photo_manager/photo_manager.dart';

class MediaServices {
  Future loadAlbum(RequestType requestType) async {
    var permission = await PhotoManager.requestPermissionExtend();
    List<AssetPathEntity> albumList = [];
    if (permission == true) {
      albumList = await PhotoManager.getAssetPathList(
        type: requestType,
      );
    } else {
      PhotoManager.openSetting();
    }
    return albumList;
  }
  Future loadAssets(AssetPathEntity selectedAlbum) async {
  // ignore: deprecated_member_use
  List<AssetEntity> assetList = await selectedAlbum.getAssetListRange(
      // ignore: deprecated_member_use
      start: 0, end: selectedAlbum.assetCount);
      return assetList;
}

}

  1. Best Answer

    使用pub.dev 的权限处理程序插件，这是类似的答案

    对于 android，在 Androidmainfest.xml 文件中添加这些行

    <uses-permission android:name="android.permission.READ_INTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permissionandroid:name="android.permission.MANAGE_EXTERNAL_STORAGE"/>

    对于 iOS，在 info.plist 文件中添加以下代码

    <key>NSMicrophoneUsageDescription</key>
<string>This app require permission to access microphone</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app require permission to access gallery</string>

    相应修改以下代码。

     Future<void> getStorageReadPermission() async {
    final storage = await Permission.storage.status;
    !storage.isGranted
        ? await Permission.storage.request()
        : debugPrint("Storage read permission already granted");
  }

  Future<void> getStorageManagePermission() async {
    final manageStorage = await Permission.manageExternalStorage.status;
    !manageStorage.isGranted
        ? await Permission.manageExternalStorage.request()
        : debugPrint("storage permission already granted");
  }

  2. 最后我发现我在代码中遗漏了一些东西。我再次观看了视频，我意识到这一点。我必须输入“if(permission.isAuth==true)”而不是“if(permission==true)”。

    而不是这个

    import 'package:photo_manager/photo_manager.dart';

class MediaServices {
  Future loadAlbum(RequestType requestType) async {
    var permission = await PhotoManager.requestPermissionExtend();
    List<AssetPathEntity> albumList = [];
    if (permission == true) {
      albumList = await PhotoManager.getAssetPathList(
        type: requestType,
      );
    } else {
      PhotoManager.openSetting();
    }
    return albumList;
  }
  Future loadAssets(AssetPathEntity selectedAlbum) async {
  // ignore: deprecated_member_use
  List<AssetEntity> assetList = await selectedAlbum.getAssetListRange(
      // ignore: deprecated_member_use
      start: 0, end: selectedAlbum.assetCount);
      return assetList;
}

    我必须用这个

    import 'package:photo_manager/photo_manager.dart';

class MediaServices {
  Future loadAlbum(RequestType requestType) async {
    var permission = await PhotoManager.requestPermissionExtend();
    List<AssetPathEntity> albumList = [];
    if (permission.isAuth == true) {
      albumList = await PhotoManager.getAssetPathList(
        type: requestType,
      );
    } else {
      PhotoManager.openSetting();
    }
    return albumList;
  }
  Future loadAssets(AssetPathEntity selectedAlbum) async {
  // ignore: deprecated_member_use
  List<AssetEntity> assetList = await selectedAlbum.getAssetListRange(
      // ignore: deprecated_member_use
      start: 0, end: selectedAlbum.assetCount);
      return assetList;
}
