getShader method

Shader? getShader(
  1. String id,
  2. Rect bounds
)

Attempt to lookup a pre-defined Shader by id.

id and bounds must not be null.

Implementation

Shader? getShader(String id, Rect bounds) {
  assert(id != null); // ignore: unnecessary_null_comparison
  assert(bounds != null); // ignore: unnecessary_null_comparison
  final DrawableGradient? srv = _gradients[id];
  return srv != null ? srv.createShader(bounds) : null;
}
