# Update Packages > [!IMPORTANT] > **Sequential Execution Required**: All steps must be executed strictly one after another in sequence in a single execution context. Do **NOT** use parallel subagents or run commands concurrently across channels, as switching Flutter SDK channels modifies shared local SDK state. ## Step 1: Update allowlist (if needed) If adding or removing packages, edit `lib/src/project_templates.dart` first. This file contains the allowlist of supported packages. Skip this step if only updating versions. ## Step 2: Update dependencies for each channel Run the following sequentially for each channel (`stable`, `beta`, `main`): ```bash flutter channel <CHANNEL> flutter upgrade dart tool/grind.dart update-pub-dependencies ``` ## Step 3: Switch back to stable ```bash flutter channel stable ``` ## Step 4: Verify changes Check `git status` and `git diff` to confirm the expected changes to `tool/dependencies/pub_dependencies_stable.json`, `pub_dependencies_beta.json`, and `pub_dependencies_main.json`.
