TypingStatically typed with strong, sound type inference and no null values.Statically typed with sound null safety (optional in older versions), and supports type inference.
PerformanceRuns on the BEAM (Erlang VM), offering excellent concurrency and fault tolerance, but not focused on raw computational speed.Compiled to native code (via Dart VM or AOT) or JavaScript for web, offering high performance especially in Flutter apps.
Libraries and frameworksSmaller ecosystem, mainly focused on backend and concurrent applications; limited libraries and frameworks.Rich ecosystem, especially strong for UI development with Flutter, and a wide range of libraries for web, server, and mobile.
Community and supportGrowing but small community, limited resources and third-party support.Large and active community, strong backing from Google, extensive documentation and support.
Learning curveSteeper for those unfamiliar with functional programming; simple syntax but new concepts for many developers.Gentle for those with experience in C-style languages; familiar syntax and concepts for most developers.
