Isolates launched by the engine instance use the settings of that instance. (#22052) This regression was introduced in https://github.com/flutter/engine/pull/21820 for sound-null safety. The settings used to launch the VM were incorrectly used to determine the isolate lifecycle callbacks. Since the first shell/engine in the process also starts the VM, these objects are usually identical. However, for subsequent engine shell/engine launches, the callbacks attached to the new settings object would be ignored. The unit-test harness is also structured in such a way that each test case tears down the VM before the next. So all existing tests created a bespoke VM for the test run, and, the tests that did create multiple isolates did not also test attaching callbacks to the settings object. Fixes https://github.com/flutter/engine/pull/22041
Flutter is Google's mobile app SDK for crafting high-quality native interfaces in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.
