Install the Flutter plugin if you don't already have it installed. This can be done via the normal Plugins
page in the IntelliJ and Android Studio settings. Once that page is open, you can search the marketplace for the Flutter plugin.
In order to open DevTools, you typically first want to run a Flutter app. This can be accomplished by opening a Flutter project, ensuring you have a device connected, and hitting the Run
or Debug
toolbar buttons.
Once an app is running, you can start DevTools by:
Open DevTools
toolbar action in the Run viewOpen DevTools
toolbar action in the Debug view (if debugging)Open DevTools
action from the More Actions
menu in the Flutter Inspector viewYou can also open DevTools from an IntelliJ action. Open the Find Action...
dialog (on a Mac, type cmd-shift-a
), and search for the Open DevTools
action. When you select that action, DevTools will be installed, the DevTools server launched, and a browser instance will open pointing to the DevTools app.
When opened via an IntelliJ action, the app will not be connected to a Flutter app. You'll need to provide it with a service protocol port for a currently running app; this can be done via the in-line Connect to a running app
dialog.
