Unable to locate a development device; please run 'flutter doctor' .. but doctor checks out ok

Question

A new installation of flutter/dart went smoothly without issue .. running "flutter doctor -v" gives the following output:

 $ flutter doctor -v

[!] Connected device

! Doctor found issues in 1 category.

and yet attempting to run the defalut starter app "flutter/material.dart" results in ... "Unable to locate a development device; please run 'flutter doctor' for information about installing additional components" ... irrespective whether i use Intellij or Visual Studio.

However,

$ flutter devices
1 connected device:

Pixel XL • HT69R0205363 • android-arm64 • Android 9 (API 28)     

I have searched the web and found similar complaints .. but no solution. I was hoping that someone might be able to throw some light on this as I am sure it must be something simple and straight forward.

Visual Studio is a new installation but I have been using Intellij now for 6 months on a daily basis and rarely have issue with it .. especially one that i cannot fix. :)

Thank you in advance.

Solution 1

open Terminal in Android Studio or VS Code.

and writes this command :

flutter config --android-sdk <sdk-location>

SDK-location is your Path for SDK! for Example :

flutter config --android-sdk /home/sanaebadi/Pasport/programming/and_dev/sdk/sdk-tools-linux-3859397/

Solution 2

I had the same problem , then I tried this solution , and it helped me and my flutter app is running on my phone ..

all you need to do is install Android API level 29 (Android 9.0+ "Q") go to Setting > Android SDK >SDK platform>Check Android 9+ and Press Apply button

I found this solution from github .. her is the link .. Hope this help you

flutter config --android-sdk <sdk-location> ,sdk is in lower case

I test this command and is correct. maybe with lowercase is correct too
