fetchSavedBridges static method

Future<List<Bridge>> fetchSavedBridges({ String decrypter(String ciphertext)?, Directory? directory, })

Fetch all of the bridges already saved to the user's device.

decrypter When the bridge data is read from local storage, it is decrypted. This parameter allows you to provide your own decryption method. This will be used in addition to the default decryption method. This will be performed after the default decryption method.

directory The directory where the bridge data will be saved. If this is not provided, the default directory will be used.

If the bridges are not saved to the default folder location, provide their location with directory.
