Here are several articles that discuss useful keyboard bindings to speed up Flutter app development in IntelliJ. Note that “Android Studio” is just IntelliJ with a specific set of plugins, so all of these apply if you are using IntelliJ Ultimate.
There’s some redundancy but I think each article has some unique recommendations:
Enable Terminal in Preferences/Plugins, as it is disabled by default. Then the terminal icon appears in bottom of screen. This provides an in-IDE terminal which defaults to the project directory location. Very useful.
IntelliJ has an annoying habit of popping up a notification to ask if you want to apply the official Kotlin style when you open a new Flutter project. To get rid of this, go to Preferences/Appearance and Behavior/Notifications, find “Kotlin official code style available” and set the Popup type: to “No popup”.
Go to Settings-Languages and Frameworks-Flutter, and enable:
By default IntelliJ does not provide a “Create directory” option inside the lib/ folder, which is horrible. To fix this, go to File - Project Structure - Module. Then click the lib/ directory and unmark it as sources.

Let’s say you are developing an app named ‘foo’ and you need to import a file from another directory. You could use “absolute” import as follows:
import 'package:foo/app/home/models/bar.dart';
Instead, use a “relative” import:
import '../../models/bar.dart';
Don’t adopt a personal style for code formatting. Instead, use Option-Command-L to format the code according to the “official” guidelines. It might not be exactly the way you prefer (it isn’t for me), but you won’t spend time on formatting, and the official approach is good enough.
Besides, your code will be formatted automatically on save anyway.
