What methods do you use to determine the order of task execution?

Answer from AI
In Flutter, the order of task execution can be controlled in several ways:
- Using asynchronous functions with
async/awaitfor sequential execution. - Working with
Futureand methods likethen(),whenComplete()to handle results and chains. - Using
Streamfor processing sequential events. - Scheduling tasks via
SchedulerBindingorWidgetsBindingto execute code at specific moments in the widget lifecycle.
Example of sequential execution with async/await:
Future<void> fetchData() async {
var data = await getDataFromNetwork();
print(data);
}
void main() async {
await fetchData();
print('Data fetched');
}
This guarantees that print('Data fetched') will execute after the data is received.
