Here is the android manifest as requested

   <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="finosellapp"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
          
            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
          
            <meta-data
              android:name="io.flutter.embedding.android.SplashScreenDrawable"
              android:resource="@drawable/launch_background"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>

Because file_picker currently doesn't support scoped storage, you'll need to set android:requestLegacyExternalStorage="true" on your AndroidManifest.xml file, under :

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.app.www.app">
    <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="finosellapp"
        android:requestLegacyExternalStorage="true"
        android:icon="@mipmap/ic_launcher">
       
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">

            <meta-data
                android:name="io.flutter.embedding.android.NormalTheme"
                android:resource="@style/NormalTheme"
                />

            <meta-data
                android:name="io.flutter.embedding.android.SplashScreenDrawable"
                android:resource="@drawable/launch_background"
                />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>

Add this one to your Android Manifest file

android:requestLegacyExternalStorage="true" 

And Change app compileSdkVersion to 28 in filepicker build.gradle file. To get this file you requested to open MainActivity.class file in andriod folder at right corner Open for Editing android studio click on that it open as new android project. then select file filepicker build.gradle file.

Hope this will help to you.

I struggle with this issue past 5days, now only I fixed.

What's you issue? @LizardKing_96

[LizardKingLK]

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility. Building plugin file_picker...

[LizardKingLK]

I followed the instructions given by the issues page and it did not help. flutter.dev/docs/development/androidx-migration

[Amon C]

That could be another case. There are different settings when you use AndroidX and when not. Ask a question and comment here I will try to help.
