Dart Isolates Deep Dive — compute, SendPort, and Parallel Processing Patterns

Dart Isolates Deep Dive — compute, SendPort, and Parallel Processing Patterns Dart's main thread runs on a single-threaded event loop. CPU-heavy work blocks that loop, freezing your UI. Isolates are Dart's answer to parallelism — and their "no shared memory" design eliminates entire classes of bugs that plague threaded systems. Why Isolates? // This blocks the UI thread for seconds on large datasets List int > heavySort ( List int > data ) { data . sort (); return data ; } async/await is concurr
