An Isolate object provides information about one isolate in the VM.

Implemented types


Isolate({required String? id, required String? number, required String? name, required bool? isSystemIsolate, required List<IsolateFlag>? isolateFlags, required int? startTime, required bool? runnable, required int? livePorts, required bool? pauseOnExit, required Event? pauseEvent, required List<LibraryRef>? libraries, required List<Breakpoint>? breakpoints, required String? exceptionPauseMode, LibraryRef? rootLib, Error? error, List<String>? extensionRPCs})
