GetBackend()

IOSRenderingBackend flutter::IOSContextMetalSkia::GetBackend ( ) const

overridevirtual

Get the rendering backend used by this context.

Returns

The rendering backend.

Reimplemented from flutter::IOSContext.

}

GetMainContext()

sk_sp< GrDirectContext > flutter::IOSContextMetalSkia::GetMainContext ( ) const

overridevirtual

Accessor for the Skia context associated with IOSSurfaces and the raster thread.

There can be any number of resource contexts but this is the one context that will be used by surfaces to draw to the screen from the raster thread.

Returns

nullptr on failure.

Attention

The software context doesn't have a Skia context, so this value will be nullptr.

See also

For contexts which are used for offscreen work like loading textures see IOSContext::CreateResourceContext.

Implements flutter::IOSContext.
