Updating Package Versions

Updating Package Versions

When updating dependency versions in published package pubspec.yaml files (devtools_shared, devtools_app_shared, and devtools_extensions), follow these rules to protect the local mono-repo workspace graph:

• Version Decisions: Decide if it should be a major, minor, or patch version based on your edits:
  • Breaking changes: Major bump (+1 to first component, others reset to 0). E.g., removals of public constants, properties, getters/setters, or APIs.
  • New features or deprecation start: Minor bump (+1 to second component, patch resets to 0).
  • Bug fixes and non-breaking changes: Patch bump (+1 to third component).
• Match Exact Versions: Always use the actual version specified in the target package's pubspec.yaml file.
• Suffix Preservation: If a requested version contains a suffix like -wip (e.g., 13.0.0-wip), the full string MUST be used in dependency constraints (e.g., devtools_shared: ^13.0.0-wip).
• Prevent Graph Failures: Do not drop the suffix or estimate the base version tags. Version solver operations will fail in the local workspace if dependencies point to published strings that can't be resolved in non-published repositories.
• No Dependencies on Unpublished Packages: Published packages (devtools_shared, devtools_app_shared, and devtools_extensions) MUST NOT depend on unpublished packages like devtools_app or devtools_test.
• Resolution Testing: After updating versions, run flutter pub get in the repository to ensure version solving is satisfied. If this returns errors, you should fix the errors and try again.
• Updating devtools_app: In packages/devtools_app/pubspec.yaml:
  • Dependencies on published packages do not have version constraints. This is intentional; do not change this when updating versions.
  • Always use the dt update-version tool to update the devtools_app version.
  • This should only be updated for monthly releases and cherry pick releases, so perform this update only when explicitly asked to.
