ShaderPaint class

A pass painted by one of the project's own fragment shaders.

asset is the shader's key in the bundle — the path its pubspec declares under flutter: shaders:, and what FragmentProgram.fromAsset takes. uniforms are the author's values by name, one to four floats each (a float, a vec2, a vec3, a vec4). The renderer sets rendererUniforms itself, and a name the shader does not declare is skipped, never thrown.

What the renderer sets, by name and float count, when the shader declares it at that size: the box's logical size (the whole text, or one line), the text's own colour as straight RGBA 0–1, and scene seconds. A shader that does not declare one simply does not get it.
