ShaderUniforms class

Runtime values passed to a fragment shader for one paint cycle.

Use floats for numeric uniforms and sampler2Ds for texture uniforms. version is used by painters to detect uniform changes efficiently.

Constructors

ShaderUniforms({Map<String, double> floats = const {}, Map<String, Image> sampler2Ds = const {}, int version = 0})
