+	  // Permission.storage.request();
+	  // var status = await Permission.camera.request();
+
+	  if (status.isDenied) {
+		print('storage permission denied');
+	  } else if (status.isGranted) {
+		print('storage permission granted');
+	  }
+	}

+  - also in `AndroidManifest.xml` , add following
+   for below android 11
+   ```xml
+	<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

+   for  above andoid 11
+	 ```xml
+	<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/>
