Flutter Widgets Probably Haven’t Heard Of
summary
Shows ten concrete Flutter tools and what they actually do: turning heavy CustomPainter output into a static image with snapshot widget or by using RepaintBoundary.toImage for both performance and screenshots, using CompositeTransformTarget/Follower plus LayerLink to attach dropdowns that follow a moving target, toggling animations cleanly with TickerMode, using GridPaper for pixel alignment, a built-in shape for beveled/curved corners, SensitiveContent to block screenshots on Android, BlockSemantics for accessibility, and a linked repository of test cases.
