check out receive_sharing_intent

and add below code in your manifest

    <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"
        android:maxSdkVersion="28"/>
 

   <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
