customLayoutId property
The custom ID of a grid configured for this flow in the Adapty Flow Builder, to render instead of the grid selected automatically for the current device.
Pass null to keep the automatic selection. The ID is matched exactly as
given. An unknown ID leaves the embedded native view unconfigured and
empty; the failure is only reported to the native log.
Like every other creation parameter of this widget, it is read once when the native view is created. Changing it on a mounted widget has no effect — rebuild the widget under a different Key to render another grid.
Implementation
final String? customLayoutId;
