I can\'t click the run button. Does anyone know how to fix it?
You have to reconfigure the FlutterSDK path in Android Studio: Go to Setting -> Language & Frameworks -> Flutter and set the path to Flutter SDK
If your IDE is in power save mode, then the run button etc. are also disabled.
You can verify this via the file -> power save mode, make sure it is disabled.
for flutter project, if the run button is disabled then you have to
tools>> flutter>> flutter packages get >>enter your flutter sdk path >>finish
This should solve your problem...
It was quite silly for me, I just opened the Run > Run Configurations window everything seemed to be fine there, I didn't change anything, when I closed the window the button was enabled.
My solution was to go to that multiselect button, then "Edit Configurations" -> Go to "+" and select the module (in this case it would be an app if you do not have a multiproject -> then apply and OK
Above answer didn't work for me, just do click File -> Invalidate/cache -> Invalidate and Restart.
