summary
The talk explains Flutter’s new official two-dimensional scrolling support (TwoDimensionalScroll) and how it replaces previous “hacky” approaches. It describes when to use the built-in solutions versus implementing a custom 2D scroll, discusses performance implications, and shows concrete optimizations applied to a complex video-editor case (Yappy) that in some scenarios boosted FPS by up to 10×, plus a demo custom implementation used in the Mobius schedule app.
