flutter-implement-json-serialization skillA

flutter-implement-json-serialization is agent-read markdown (skill) from sutchan/agent-skills-hub: Create model classes with `fromJson` and `toJson` methods using `dart:convert`. Use when manually mapping JSON keys to class properties for simple data structures..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sutchan/agent-skills-hub/flutter-implement-json-serialization@git:20260909.998370c
Exact content
mdr add sutchan/agent-skills-hub/flutter-implement-json-serialization@sha256:05a4478e0a3d119f

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
