Flutter-intellij: Cannot find runner for flutter

[thosakwe]

Issue

I cannot execute any Flutter run configurations - the run button is disabled. When I used Alt+Shift+F10 to force run, I saw the underlying error: "Cannot find runner for angel_flutter".

So, for some reason, there is no runner available for the run configuration. I have also created other configurations, and receive the same result every time.

I don't know what a "runner" is here, but it's missing. No idea why.

Steps to Reproduce

1. Create an IntelliJ (using WebStorm 2017.1 here) project, with more than one Dart project in it.
   My structure right now:

backend/ - Backend server with Angel framework
client/ Virtually untouched base Flutter app from 'flutter create' - just changed title, added one dependency
common/ - Shared model files

See the project: https://github.com/angel-example/flutter

I have since upgraded to Dart 1.23.0, not sure if that has anything to do with it.

ideviceinstaller is actually installed - I've installed it literally dozens of times, but it always reports that.

Thanks in advance!!!

Looking at the git repo, looks like you have three elements here: 2 dart (backend and common) and 1 flutter (client)?

I believe what you need is an IntelliJ project with three modules in it; 2 dart modules and 1 flutter module. I also believe this is only supported in IDEA, and not WebStorm. @devoncarew can you confirm?

Also note that you need to install the Flutter and Dart plugins into your IDEA; looks like they are missing.

[devoncarew]

As @mit-mit, said, I would confirm in your IntelliJ that you have the Dart and Flutter plugin installed, that you have version 13.0 of the Flutter plugin, and then would create a new launch configuration for your flutter app, and connect a device or start the iOS simulator. With all that, you should see a device pulldown on the IntelliJ toolbar, and when the Flutter launch configuration is selected, the run and debug buttons should be enabled.

@mit-mit @devoncarew I have both plug-ins. I'll try this in IntelliJ IDEA, though, maybe it doesn't work for WebStorm.

Also, @devoncarew, my phone was connected while I was receive these errors. I'll try again with the iOS Simulator running, hopefully that will work.

Update: There's actually nothing wrong with the project configuration.

It turns out that you can't run a Flutter application unless it is at the root of your application. Please correct me if I am wrong.

I have mine in client/ and thus have to run it via the command-line.

@thosakwe not sure I fully understand what is not working for you. The following works for me:

1. Start IntelliJ IDEA
2. File > New > Project
3. Select Flutter, click Next
4. Set Project name to ProjectOne
5. Expand More Settings, and change Module name to client. Leave remaining values as they are. Hit Finish
6. Run > Edit Configurations, rename from main.dart to client
7. File > New > Module
8. Select Dart + console template
9. Change module name to server, and hit Finish
10. Run > Edit Configurations, expand Dart, rename from main.dart to client

=> you can now either launch client or server by selecting the config and hitting Run or Debug

Okay, thank you! I'll have to run this in IDEA, rather than WebStorm.

you can try this ,
tools>> flutter>> flutter packages get >>enter your flutter sdk path >>finish .

Each time this thing happens in my Android Studio, I restart IDE and make it update, as well as Flutter and Dart plugins. Bad UX, of course.

you can try this ,
tools>> flutter>> flutter packages get >>_enter your flutter sdk path_ >>finish .

this will get you to a configuration window, where you can select the location of the flutter installation. this will do the trick in some cases
