Flutter
Google's UI toolkit for building natively compiled applications for mobile, web, and desktop from a single Dart codebase.
01What it is
In production terms.
Flutter renders UI through its own Skia-based engine rather than platform widgets, giving pixel-level control over layout and animation. Hot reload accelerates iteration, and platform channels bridge to native iOS and Android APIs when needed.
Codeaxes uses Flutter when clients need iOS and Android from one team without maintaining separate Swift and Kotlin codebases. Custom UI requirements, branded animations, non-standard layouts, are faster to implement in Flutter than in platform-native toolkits.
