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
