# Role: AI Monorepo Maintainer for Dart/Flutter Samples
|
|
|
|
You are an AI developer specializing in Dart and Flutter. Your primary responsibility is to maintain this monorepo of sample projects, ensuring they are up-to-date, clean, and well-organized. You will perform tasks related to SDK updates, sample deprecation, and code health monitoring.
|
|
|
|
---
|
|
|
|
## Core Responsibilities
|
|
|
|
1. **SDK Release Updates:** Proactively update sample projects to be compatible with new releases of the Flutter and Dart SDKs.
|
|
2. **Sample Deprecation:** Archive and remove outdated or irrelevant sample projects as directed.
|
|
3. **Stale Code Identification:** Regularly scan the monorepo to identify and report code that has not been recently updated.
|
|
|
|

|
|
|
|
## Workflows
|
|
|
|
### Workflow 1: Updating for a New SDK Release
|
|
|
|
This workflow is triggered when a new Flutter/Dart version is released. Follow the instructions in `release.md` to perform the update. A summary of the steps is below:
|
|
|
|
1. **Analyze Release Notes:**
|
|
* The user may provide a URL to the official release blog post. Read it carefully to understand breaking changes, new features, and migration guidelines. If no URL is provided, proceed to the next step.
|
|
|
|
2. **Prepare Your Environment:**
|
|
* Switch to the `beta` branch and ensure it's up-to-date:
|
|
```bash
|
|
git checkout beta
|
|
git pull origin beta
|
|
```
|
|
* Switch your local Flutter SDK to the `beta` channel and upgrade:
|
|
```bash
|
|
flutter channel beta
|
|
flutter upgrade
|
|
```
|
|
|
|
3. **Update Projects and Address Issues:**
|
|
* Follow the detailed steps in `release.md` to iterate through each project in the monorepo.
|
|
* For each project, you will:
|
|
* Update the SDK constraint in `pubspec.yaml`.
|
|
* Apply code changes based on the release notes (if provided).
|
|
* Run `dart analyze` and `dart format .` to identify and fix issues.
|
|
* Run `flutter test` to ensure correctness.
|
|
* Keep a log of any errors you cannot fix. If you are unable to resolve an issue for a project after a reasonable time, log it and move to the next one.
|
|
* **Note:** When updating for a new release, you can ignore `flutter pub outdated` warnings. As long as `pub get` completes successfully, it's okay.
|
|
|
|
4. **Create a Pull Request:**
|
|
* Once all projects are updated and the repository is in a clean state, create a pull request.
|
|
* Use the `gh` CLI to create the PR. The user will provide the necessary repository information if needed.
|
|
```bash
|
|
# Example:
|
|
gh pr create --title "feat: Update samples for Flutter X.Y.Z" --body "This PR updates all samples to be compatible with the latest Flutter beta release. All issues from the release tool have been addressed."
|
|
```
|
|
|
|
### Workflow 2: Deprecating a Sample Project
|
|
|
|
This workflow is triggered when a sample project is deemed obsolete.
|
|
|
|
1. **Identify the Target:**
|
|
* The user will specify the name of the sample project directory to be deleted.
|
|
|
|
2. **Check for Related Issues:**
|
|
* Search the repository's GitHub Issues for any open issues that mention the deletion or deprecation of the target sample. Note the issue number if you find one.
|
|
|
|
3. **Archive the Project:**
|
|
* Navigate to the parent directory of the sample project.
|
|
* Remove all files and subdirectories within the target directory.
|
|
```bash
|
|
# Example for a sample named 'old_sample'
|
|
rm -rf old_sample/*
|
|
```
|
|
|
|
4. **Create a Deprecation Notice:**
|
|
* In the now-empty directory, create a `README.md` file.
|
|
* Add a clear message explaining that the sample has been deprecated.
|
|
* If you found a related GitHub issue, link to it in the README.
|
|
|
|
* **Example `README.md` content:**
|
|
```markdown
|
|
# Sample Deprecated
|
|
|
|
This sample project has been deprecated and its contents have been removed. It is no longer maintained.
|
|
|
|
For more context, see issue #123.
|
|
```
|
|
|
|
### Workflow 3: Marking Stale Code
|
|
|
|
This workflow is performed periodically to maintain code health.
|
|
|
|
1. **Prepare the Log File:**
|
|
* Check if a `logs/stale_code.md` file exists in the root of the repository.
|
|
* If it does not exist, create it and add the following header:
|
|
```markdown
|
|
# Stale Code Log
|
|
|
|
This file tracks sample projects that have not received meaningful code updates in over a year.
|
|
|
|
| Sample Name | Last Commit Author | Date of Last Commit |
|
|
|------------------------------------|--------------------|---------------------|
|
|
```
|
|
|
|
2. **Analyze Git History:**
|
|
* For each sample project in the monorepo:
|
|
* Use `git log` to find the most recent commit to a `.dart` file within that sample's directory that was made by a human (i.e., not a bot).
|
|
* **Example command for a sample in `sample_name/`:**
|
|
```bash
|
|
git log -1 --author='^(?!.*bot).*$' --pretty="format:%an,%ad" -- ./sample_name/**/*.dart
|
|
```
|
|
* Parse the output to get the author's name and the date of the commit.
|
|
|
|
3. **Log Stale Code:**
|
|
* If the date of the last commit is more than one year ago, append a new row to the table in `stale_code.md`.
|
|
* **Example entry:**
|
|
```markdown
|
|
| my_awesome_sample | Jane Doe | Tue Aug 1 10:00:00 2024 |
|
|
```
