For enterprise mobile teams
One codebase. Half the maintenance.
Two native codebases cost twice the effort and twice the bugs. Learn Flutter to consolidate into one typed, testable, maintainable codebase.
Consolidate native codebases
Flutter compiles to native ARM code. Replace separate iOS and Android projects with one Dart codebase that performs identically.
Enterprise architecture patterns
MVVM, SOLID, dependency injection. The patterns your team already uses, applied to Flutter's widget system.
Faster iteration cycles
Hot reload during development. One PR ships to every platform. Features reach users in half the time.
Flutter + SOLID + DRY + MVVM
Production architecture for enterprise mobile teams.
