Modifier: embracing Compose-inspired UI in Flutter
summary
Proposes a Compose-style Modifier implemented as a plain Dart class with mutable, copyable configs and deep equality; shows a reusable Modified wrapper that applies padding, background, alignment and alpha by composing standard Flutter widgets so the render tree and performance stay intact. Compares that to extension helpers and per-widget modifier APIs, demonstrates that order matters for effects, and reports that most Compose modifiers can be replicated in Flutter though scope safety (e.g. Expanded only valid in certain parents) is not enforced.
