runtimeShaderSdk top-level constant

String const runtimeShaderSdk

The text a ShaderBundle built at run time carries in its sdk field.

No backend that loads a run-time bundle compares it — the software rasteriser and WebGL2 compile nothing ahead of time — and the one that does, Impeller, never gets one: runtimeMaterialBundle refuses it first.

Implementation

const String runtimeShaderSdk = 'flutter3d run time';
