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
# Previewing Flutter Widgets ## Contents - [Preview Guidelines](#preview-guidelines) - [Preview Parameters](#preview-parameters) - [Handling Limitations](#handling-limitations) - [Workflows](#workflows) - [Examples](#examples) ## Preview Guidelines Use the Flutter Widget Previewer to render widgets in real-time, isolated from the full application context. - **Target Elements:** Apply the `@Preview` annotation to top-level functions, static methods within a class, or public widget constructors/factories that have no required arguments and return a `Widget` or `WidgetBuilder`. - **Imports:** Always import `package:flutter/widget_previews.dart` to access the preview annotations. - **Custom Annotations:** Extend the `Preview` class to create custom annotations that inject common properties (e.g., custom themes, wrappers, sizes) across multiple widgets. - **Multiple Configurations:** Apply multiple `@Preview` annotations to a single target to generate multiple preview instances. Alternatively, extend `MultiPreview` to encapsulate common multi-preview configurations. …

How to install
mdr add sutchan/agent-skills-hub/flutter-add-widget-preview@sha256:da257f97d23bb0ffThe line at the top of this page pins the label git:20261029.81273f9, 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.
