Subject: [PATCH] fix(android): add app_flutter path for FileProvider
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

APK downloaded to getApplicationDocumentsDirectory() which maps to
files/app_flutter/ on Android. FileProvider needs this path configured
to grant URI permission for APK installation.
