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

• Run yarn flow $ARGUMENTS (use dom-node if no argument)

• Report type errors with file locations

• 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
