This is a tracking issue for implementing the Material components in Slint.

Aims

Keep it as close to the Material 3 spec as possible. So people can reuse the existing Figma Material Design Kit, theme builder, etc.

Have a new complete component set for the Slint MPU/MCU platforms that unlike desktop, iOS or Android have no standard components. Material 3 was chosen as it's well known and has excellent touch support.

Deliver a full component set and a GALLERY that showcases them all.

The Material Components for Web Shows a much more detailed set of components. These might be useful for examples as opposed to actual extra components which might have an unreasonable maintenance burden?

Open Questions:

Support the Material theme builder? It has a JSON export option that could be converted to a Slint palette?

Meta questions

Theme support?

Layer / portal support. In React components have the ability to 'portal'. This is where they draw all or part of the UI to another layer. For example a snack bar shows over most content. A context menu may be activated by a button in VerticalLayout, but you want the menu to overlap all app content, not run under the next item in the container.

'Elevation'. This is the Android/Material property names to manage drop shadows. React Native is confusing here because it supports both systems, but only elevation works on Android. Maybe we can avoid some pain here e.g. we keep the Slint 'shadow' properties but provide a Material helper function you can use to map elevation to shadow?

Material Icons can be found here. It's a sizeable file. Anything needed to reduce it to only items the project uses, convert to bitmap on low end devices, etc?
