ShaderManager class

A singleton class that manages and caches fragment shaders for different modes.

Properties

hashCode → int
The hash code for this object.
no setterinherited
isShaderFilterSupported → bool
Whether ImageFilter.shader is supported on the current backend.
no setter
programs → Map<ShaderMode, FragmentProgram>
The loaded programs by their mode, for widgets that need a shader whose uniforms no other widget changes; see createShader.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shaders → Map<ShaderMode, FragmentShader>
A map that stores loaded shaders by their mode.
final

Methods

containsShader(ShaderMode mode) → bool
Checks if a shader for the given mode is already loaded.
createShader(ShaderMode mode) → FragmentShader?
A new shader of the loaded program for mode, or null while it is not loaded.
loadShader(ShaderMode mode) → Future<FragmentShader>
Loads a shader for the given mode. If the shader is already loaded, it returns the cached version. Otherwise, it asynchronously loads and caches the shader.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
