Shows how the Flame Shader Pipeline API and Flutter fragment shaders are wired together, using canvas paints, animated samplers and image samplers to make glass/watermorphism, fog, light reflection, mesh gradients and pixelation. Notes that imageFilter.shader is Impeller-only with strict structure, and that toImageSync can delay frames, so postprocesses must be sequenced carefully. Demonstrates a Saturn 5 launch game built with Flame postprocessing components, multiple shader passes and camera effects, which runs and will be open sourced.
