MigrationTipView class

Embeds the native iOS migration tip view (MigrationTipView from ZeroSettleKit) inside a Flutter app.

The native SwiftUI view is intrinsically self-sizing — its height changes based on event state (CTA swap when Apple Pay needs setup, dismissal, loading state, etc.). A fixed SizedBox would either clip taller content or reserve dead space when the view collapses.

This widget subscribes to a per-view MethodChannel that the native container pushes size updates to whenever its layoutSubviews() fires. Flutter rebuilds with the new height, so the surrounding layout always matches the actual rendered content.

Renders nothing on Android.

Example:

MigrationTipView(
  userId: 'user123',
  backgroundColor: Theme.of(context).colorScheme.primary,
)

Properties

backgroundColor → Color
Used as both the card fill AND the CTA text color on the native view (the CTA button background is hardcoded white). Pass a saturated brand color, not a neutral surface — white-on-white text won't render.

key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
