Three flutter widgets you may have never used before

Three lesser-known Flutter widgets can improve your development workflow and app performance. GridPaper overlays a customizable grid to help debug alignment and spacing issues visually. TickerMode provides an on/off switch for animations in a widget subtree, conserving resources when screens are offstage. RepaintBoundary isolates widget subtrees into separate compositing layers to prevent unnecessary repaints and reduce jank. Each widget addresses specific problems: GridPaper for layout debugging, TickerMode for animation control and performance, and RepaintBoundary for optimizing rendering performance when used judiciously.
