Broken Flutter SDK >=24.1.0
Row.fromMap now does:
TypeScript
data: Map<String, dynamic>.from(map["data"] ?? {})
But Appwrite Cloud TablesDB row responses return custom row columns flattened at top level,
TypeScript
{
"supported_versions": ["1.2.4", "1.2.5"],
"$id": "..."
}
So row.data becomes {} and all custom row fields disappear. Older versions worked because they used fallback behavior like:
TypeScript
data: map["data"] ?? map
Confirmed:
- Works: 18.0.0, 20.3.0, 23.0.0, 24.0.0
- Broken: 24.1.0, 24.1.1, 24.2.0
Issue opened here: https://github.com/appwrite/sdk-generator/issues/1561
Can you also add tests to prevent stuff like this in the future?
TL;DR
Flutter SDK versions 24.1.0 and above have a bug where custom row fields disappear due to changes in Row.fromMap behavior. Appwrite Cloud TablesDB row responses have custom columns flattened at the top level. The solution is to either downgrade to a working version or wait for a fix. Issue is tracked here: https://github.com/appwrite/sdk-generator/issues/1561. Suggestions were made to add tests to prevent such issues in the future.
