Flutter पर Cloud Storage की मदद से फ़ाइलें डाउनलोड करना

// Create a storage reference from our app
final storageRef = FirebaseStorage.instance.ref();

// Create a reference with an initial file path and name
final pathReference = storageRef.child("images/stars.jpg");

// Create a reference to a file from a Google Cloud Storage URI
final gsReference =
    FirebaseStorage.instance.refFromURL("gs://YOUR_BUCKET/images/stars.jpg");

// Create a reference from an HTTPS URL
// Note that in the URL, characters are URL escaped!
final httpsReference = FirebaseStorage.instance.refFromURL(
    "https://firebasestorage.googleapis.com/b/YOUR_BUCKET/o/images%20stars.jpg");

final islandRef = storageRef.child("images/island.jpg");

try {
  const oneMegabyte = 1024 * 1024;
  final Uint8List? data = await islandRef.getData(oneMegabyte);
  // Data for "images/island.jpg" is returned, use this as needed.
} on FirebaseException catch (e) {
  // Handle any errors.
}

final islandRef = storageRef.child("images/island.jpg");

final appDocDir = await getApplicationDocumentsDirectory();
final filePath = "${appDocDir.absolute}/images/island.jpg";
final file = File(filePath);

final downloadTask = islandRef.writeToFile(file);
