flow

Static type checking for React code across DOM and native platforms. Arguments: - Four renderer options cover standard DOM, browser-specific code, React Native, and Fabric environments - Run yarn flow with optional renderer argument; use yarn flow-ci for comprehensive but slower checks - Reports type errors with file locations to help identify and fix issues quickly - Watch for common pitfalls: missing renderer specification, unexamined $FlowFixMe suppressions, and incorrect type imports - $ARGUMENTS: Renderer to check (default: dom-node) - Run yarn flow $ARGUMENTS (use dom-node if no argument) - Report type errors with file locations - For comprehensive checking (slow), use yarn flow-ci - 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
