Why Dart was selected for Flutter?

  • Smooth transition animations at 60 fps (best for game dev)
  • Automatically does Garbage Collection
  • Compilation and Execution in Dart:
    • uses JIT and AOT compilation
    • JIT used during development (Hot Reload) and AOT (during release build) which compiles Dart code to Native machine code
  • HOT RELOAD
    • uses JIT compilation and builds the app within a second
  • Easy syntax similar to c++ and java
- Almost all Modern programming languages can do these, what's special about Dart?

+ It's capability to transpile dart code that can target different architectures(runtimes) and hardwares
+ including x86(Desktop/laptops), ARM (Mobile devices) to even JavaScript Engines(Browsers)
  • ARM = Advanced RISC(Reduced Instruction Set Computing) Machine
