encodeBytesAsDataURL property
If true, a bytes (Uint8List) field is stored as a DataURLBase64
string, by normalizeEntityJSON.
The adapters that encode the objects as JSON (directory, GCS) need it,
as JSON has no bytes type. DBObjectMemoryAdapter keeps the objects in
memory, so it stores the bytes as they are (overriding it as false).
Implementation
@protected
bool get encodeBytesAsDataURL => true;
