Answer a few questions about the render object you need — children, paint, hit testing, sizing — and RenderKit produces a Flutter skeleton tailored to your answers, backed by AI skills trained on render object patterns and a battery of tests to validate what you build.
RenderKit's skills understand the render object lifecycle, not just Flutter syntax — so the code it generates follows the conventions real render objects need.
Turns your answers about children, paint, and hit testing into a working RenderBox or RenderSliver subclass.
Knows when a render object needs specified constraints versus an intrinsic size, and lays out performLayout accordingly.
Flags when a render object needs a compositing layer, and generates the matching paint and hit-test overrides.
Every generated render object comes with a matching test suite, so you can confirm it behaves correctly before it ships.
Verifies constraint handling, intrinsic sizing, and dry layout against the inputs you specified.
Golden-image comparisons and a paint call inspector to catch unexpected canvas operations.
Confirms the render object reports hits exactly where you said it should be hittable — and nowhere else.
Checks that the semantics tree your render object describes is complete and accessible.
