post-fix assignment (highly useful for declarative layouting ,in flutter)

[atototenten]

why ?
to move the decl. closer to the usage ,instead of far-away ,especially prevalent in real-world flutter usage (non fortune-500)

use-case/example/syntax :

return ClipRRect(
  borderRadius: BorderRadius.all(
    Radius.circular(12)
  ) => final border_radius,
  child: DecoratedBox(
    decoration: BoxDecoration(
      borderRadius: border_radius,
      color: color,
    ),
    child: child,
  ),
);

vs.

final border_radius = BorderRadius.all(
  Radius.circular(12)
);

// 500+ lines later

return ClipRRect(
  borderRadius: border_radius,
  child: DecoratedBox(
    decoration: BoxDecoration(
      borderRadius: border_radius,
      color: color,
    ),
    child: child,
  ),
);

thanks

Don't love the syntax.
