[Solved] How do I create a flutter project despite the error "At least one platform must be selected"?

Question

Asked by Nikko on February 02, 2021 (source).

I'm trying to create a new Flutter project in IntelliJ and I get the error "At least one platform must be selected"

I followed the instructions from the Flutter website: ( here and here) However when I click on 'Finish' I receive the error shown and in the specified place just an empty folder is created.

Example from start to end:

  • Install the Flutter and Dart plugins from the IntelliJ marketplace

  • Click on "Create New Project" and choose Flutter from the list on the left

  • Flutter SDK path is prefilled to /home/nikko/snap/flutter/common/flutter (see note on flutter), so I click Next

  • set name: tryseven, location: ~/Folders/Me/Programming/Mobile/Flutter/tryseven,

    • type: Application,
    • organization: com.example
    • android language: Java
    • iOS language: Swift
    • create project offline: False
  • the "More settings" tab wasn't changed, default project format is .idea (directory based)

  • Click finish and I get the error. When I go to ~/Folders/Me/Programming/Mobile/Flutter/tryseven the directory is created and is empty

Notes:

flutter --version returns

Flutter 1.22.6 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 9b2d32b605 (11 days ago) • 2021-01-22 14:36:39 -0800
Engine • revision 2f0af37152
Tools • Dart 2.10.5

and if I change the "Flutter SDK path" to something else I get the warning "Flutter SDK is not found in the specified location." So Flutter should be set correctly


using Ubuntu 20.04.1 LTS 64-bit

and IntelliJ IDEA v.2020.1.4

IntelliJ doesn't open after I close it, I need to kill the process first, even though the window is closed. Not sure if that impacts in any way, but I'll reinstall the IDE


What I've tried without success:

  • changing the language to Kotlin or C
  • changing the organization to test.org
  • changing the type to Package (language and organization selection are disabled)
  • changing "Create project offline" to True

Just the temporary solution create project with cmd

flutter create my_app

must have flutter environment set in your OS. Then open with intellij project by browse my_app directory.
