How to select any file/file path in android - Flutter
问题
I have an app, and I need to choose files like PDF JSON, etc. First, I export my file, and then I can import it. To do this, I use the file_picker package with the below codes. Now the question is, I can pick any file's path in iOS, but on the Android side, I can not select the file or file path directly, even though I give permission in the AndroidManifest.
在iOS上，当我从file_picker触发pickFile()函数时，它正常工作。在Android部分，当我触发该函数时，它会打开文件，但我无法直接选择路径或文件。即使我在AndroidManifest中授予了权限。
Here are the codes that I use:
以下是我使用的代码：
final result = await FilePicker.platform.pickFiles(
type: FileType.custom,
allowedExtensions: ['json'],
);
Here, after getting the result I check the other conditions. Right now the problem is, as I said, I cannot get the file/file path from the Android side specifically.
在这里，获取结果后，我会检查其他条件。现在的问题是，正如我所说的，我无法从Android端获取文件/文件路径。
Android Manifest section:
Android清单部分：
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION" />

in iOS, when I trigger pickFile() function from the file_picker, it works as well. In the Android section, when I trigger the function, it opens the files, but I can not select the path or file directly. Even I can not see Flutter's application folder.

<uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION" />

为了限制对共享存储的广泛访问，请针对Android 11（API级别30）或更高版本，通过MANAGE_EXTERNAL_STORAGE权限请求所有文件访问权限。
要在将WRITE_EXTERNAL_STORAGE添加到AndroidManifest.xml后执行此操作，请将[permission_handler][1]包添加到您的应用程序并像这样请求权限：
void requestPermission() {
await Permission.manageExternalStorage.request();
}
英文:
To limit broad access to shared storage, target Android 11 (API level 30) or higher, request all-files access through the MANAGE_EXTERNAL_STORAGE permission.
To do that after adding WRITE_EXTERNAL_STORAGE to AndroidManifest.xml, add permission_handler package to your apps and Request permission like:
void requestPermission() {
await Permission.manageExternalStorage.request();
}
