Isolate
Noun · Development
Definitions
In Dart and Flutter, an independent worker with its own memory heap that runs concurrently without sharing state with other isolates, communicating only through message passing. Prevents data races by design.
In plain English: Dart's way of running code in parallel safely — each isolate has its own memory and can only talk to others by sending messages, so they can't accidentally corrupt shared data.
Example: "We offloaded the JSON parsing to a separate isolate so the UI thread stays butter-smooth."
