forgetShader function

void forgetShader(
  1. Map<String, ShaderHandle?> handles,
  2. ShaderHandle handle
)

Takes handle out of handles if it is still the one kept under its name — the release most libraries hand wrapShader. A library that frees a backend object as well does so beside it.

Implementation

void forgetShader(Map<String, ShaderHandle?> handles, ShaderHandle handle) {
  if (identical(handles[handle.name], handle)) handles.remove(handle.name);
}
