# Preparing a Pull Request Follow these steps to prepare a pull request for DevTools: 1. **Verify `dt` configuration**: - Ensure `dt` is available on the path by running `dt --help` or verifying its alias. - If not available, refer to the [CONTRIBUTING guide](../../../CONTRIBUTING.md#L64-L80) for instructions on how to set up the `dt` executable on your path. 2. **Update Flutter SDK**: - Run `dt update-flutter-sdk` to ensure the SDK is up to date. 3. **Run Presubmit with Fixes**: - Run `dt presubmit --fix` to address automated fixes. - If any issues remain or if the command fails, fix the issues manually and run `dt presubmit --fix` again to verify the fix. 4. **Run Tests for Affected Code**: - Use `git status` or `git diff upstream/master` to find changed files. - Run tests that are associated with the changed code. For example, if you edited `packages/devtools_app/lib/src/screens/logging/logging_screen.dart`, run the logging tests under `packages/devtools_app/test/screens/logging/`. ## Verification If any step fails, stop and address the issue, and then verify the issue is fixed before proceeding. > [!IMPORTANT] > Do NOT commit or push changes without getting explicit user approval first.
