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

Question

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

Answer 1

Problem is with 53.0 version of Flutter plugin for IntelliJ. You need to install previous version.

1. Download Flutter plugin from this link (https://plugins.jetbrains.com/plugin/download?rel=true&updateId=107561)
2. Open IntelliJ
3. Go to Settings
4. Click on Plugins
5. Click on Settings icon at the right corner of navbar
6. Click "Install Plugin from Disk..."
7. Select .zip file of Flutter plugin you just downloaded
8. Restart IDE

This works for me, hope this will solve your problem.
