Flutter used four primary dimensions for evaluation, and considered the needs of framework authors, developers, and end users. We found some languages met some requirements, but Dart scored highly on all of our evaluation dimensions and met all our requirements and criteria.
Dart runtimes and compilers support the combination of two critical features for Flutter: a JIT-based fast development cycle that allows for shape changing and stateful hot reloads in a language with types, plus an Ahead-of-Time compiler that emits efficient ARM code for fast startup and predictable performance of production deployments.
