packages/flutter/lib/src/material/date_picker_theme.dart:689:19

  uses `_colors.onSurfaceVariant`, a `get` getter,
      but we could use `@stableGetter` on that, too, (but that would
      then succeed because it actually has a stable body).
  Why not just change `ColorScheme.onSurfaceVariant` to
  `late final Color onSurfaceVariant = _onSurfaceVariant ?? onSurface;`
      which makes it stable.
  Or `late final Color onSurfaceVariant;` and initialize it in constructor,
      because this avoids using storage for `_onSurfaceVariant`.

packages/flutter/lib/src/material/date_picker_theme.dart:1010:16
  `rangeSelectionBackgroundColor` could probably be stable,
  uses `_colors.secondaryContainer`,
