Fragment Shaders In Flutter: A whole new World
summary
Explains how fragment shaders give per‑pixel control in Flutter using GLSL and the community package APIs shader_builder and animated_sampler, shows a working camera filter app (shade snap) that applies shaders to live frames, demos a warp stripe and a two‑image page‑flip built by capturing widgets as textures, notes real projects compile to ~20–25 concise shader lines, runs on GPU every frame so performance is fine for simple VFX but complex shaders increase battery and CPU/GPU load.
