FragmentShader class - dart:ui library

A Shader generated from a FragmentProgram.

Instances of this class can be obtained from the FragmentProgram.fragmentShader method. The float uniforms list is initialized to the size expected by the shader and is zero-filled. Uniforms of float type can then be set by calling setFloat. Sampler uniforms are set by calling setImageSampler.

A FragmentShader can be re-used, and this is an efficient way to avoid allocating and re-initializing the uniform buffer and samplers. However, if two FragmentShader objects with different float uniforms or samplers are required to exist simultaneously, they must be obtained from two different calls to FragmentProgram.fragmentShader.

Inheritance

• Object

• FragmentShader

debugDisposed → bool

Whether dispose has been called.

no setterinherited

hashCode → int

The hash code for this object.

no setterinherited

runtimeType → Type

A representation of the runtime type of the object.

no setterinherited

dispose() → void

Releases the native resources held by the FragmentShader.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

setFloat(int index, double value) → void

Sets the float uniform at index to value.

setImageSampler(int index, Image image) → void

Sets the sampler uniform at index to image.

toString() → String
