Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Serializing JSON Manually in Flutter ## Contents - [Core Guidelines](#core-guidelines) - [Workflow: Implementing a Serializable Model](#workflow-implementing-a-serializable-model) - [Workflow: Fetching and Parsing JSON](#workflow-fetching-and-parsing-json) - [Examples](#examples) ## Core Guidelines - **Import `dart:convert`**: Utilize Flutter's built-in `dart:convert` library for manual JSON encoding (`jsonEncode`) and decoding (`jsonDecode`). - **Enforce Type Safety**: Always cast the `dynamic` result of `jsonDecode()` to the expected type, typically `Map<String, dynamic>` for objects or `List<dynamic>` for arrays. - **Encapsulate Serialization Logic**: Define plain model classes containing properties corresponding to the JSON structure. Implement a `fromJson` factory constructor and a `toJson` method within the model. - **Handle Background Parsing**: If parsing large JSON documents (execution time > 16ms), offload the parsing logic to a separate isolate using Flutter's `compute()` function to prevent UI jank. …

How to install
mdr add sutchan/agent-skills-hub/flutter-implement-json-serialization@sha256:f4f48703ee2b08a1The line at the top of this page pins the label git:20261007.ab00264, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
