setFilterShader method

  1. @override
void setFilterShader(
  1. int textureId,
  2. String shaderSource
)
override

Updates the GPU-accelerated filter shader on the camera preview. Pass a valid GLSL Fragment Shader source. The shader should expect:

  • uniform samplerExternalOES sTexture
  • varying vec2 vTextureCoord

Implementation

@override
void setFilterShader(int textureId, String shaderSource) =>
    throw UnimplementedError('NitroCamera.setFilterShader');
