encodeWebGlSection function

ByteData encodeWebGlSection({ required Map<String, String> vertex, required Map<String, String> fragment, })

The section bytes for vertex and fragment sources.

Throws a StageAgreementException when a vertex stage and the fragment stage its name pairs it with (pairedFragmentStage) disagree on a varying or a uniform block: the bundle is refused with both names before a browser links the pair and draws zeros.

Implementation

ByteData encodeWebGlSection({
  required Map<String, String> vertex,
  required Map<String, String> fragment,
}) {
  requireBundleAgreement(vertex: vertex, fragment: fragment);
  final text = jsonEncode(<String, Object>{
    'vertex': vertex,
    'fragment': fragment,
  });
  return Uint8List.fromList(utf8.encode(text)).buffer.asByteData();
}
