Flow Type Checking
Arguments:
- $ARGUMENTS: Renderer to check (default: dom-node)
Renderers
| Renderer | When to Use | |----------|-------------| | `dom-node` | Default, recommended for most changes | | `dom-browser` | Browser-specific DOM code | | `native` | React Native | | `fabric` | React Native Fabric |
Instructions
1. Run `yarn flow $ARGUMENTS` (use `dom-node` if no argument) 2. Report type errors with file locations 3. For comprehensive checking (slow), use `yarn flow-ci`
Common Mistakes
- **Running without a renderer** - Always specify or use default `dom-node`
- **Ignoring suppressions** - Check if `$FlowFixMe` comments are masking real issues
- **Missing type imports** - Ensure types are imported from the correct package
