Invalid argument: Instance of 'Reference' about firebase_image HOT 1 OPEN

The problem is in image_object.dart file, with the toMap() method. The reference should call a toString() method, because the local DB does not accept Reference type.

Other problem, I found, the DB schema does not contain the reference column. It is missing in the cache_manager.dart file, in the open() method.

CREATE TABLE $table (
uri TEXT PRIMARY KEY,
remotePath TEXT,
localPath TEXT,
reference TEXT,
bucket TEXT,
version INTEGER
)

from firebase_image.
