Downloading Files
Learn and practice how to retrieve files from Firebase Storage to our local device.
Downloading files from Firebase Storage can be handled in several ways. We can use methods made available through the Firebase package or use other packages to handle and manage the download process.
The methods available through the Firebase SDK are:
Using the getData
method
The contents of a file can be immediately downloaded into memory as a byte array using the getData
method. This approach is appropriate for relatively small data, such as pictures or brief documents. If we wish to process the downloaded data right away without saving it in the local storage, the fact that the data is held in memory can be helpful. However, it’s important to note that using getData
on huge files might use up a lot of memory.
Uint8List fileData = await fileReference.getData();
// Process the fileData, e.g., display an image using Image.memory
Here, we define a fileData
variable of Uint8List
type to gather the data from the getData
method being called on the fileReference
object.
Using the getFile
method
As an alternative, we can use the getFile
method to download a file and store it on our device. This method can be used to download all types of files, including larger ones like films. This method is designed to be memory-efficient, particularly for handling substantial files. Because files are saved as temporary files on ...
