We have an early-access version of the plugin, called the dev channel. This version will be updated weekly, containing all changes made in the previous week. To use it you need to configure IntelliJ or Android Studio to look for plugins on the dev channel repository.
NOTE: If you already have the Flutter plugin installed, please uninstall it before proceeding. Once you have the plugin installed from one channel it will not be available on other channels.
Open the Plugins preference page (macOS) or settings page (Windows, Linux). Click the gear at the top-right and select Manage Plugin Repositories.
A list editor will pop up that allows you to edit custom plugin repositories. Add this to the list: https://plugins.jetbrains.com/plugins/dev/list
Then click OK. The version of the Flutter plugin you see in the Marketplace list will be the dev channel version.
