Flow Type Checking

Arguments:

  • $ARGUMENTS: Renderer to check (default: dom-node)

Renderers

RendererWhen to Use
dom-nodeDefault, recommended for most changes
dom-browserBrowser-specific DOM code
nativeReact Native
fabricReact 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
