Some problem when installing Flutter 安装过程遇到过的问题
I am an Android engineer, so I have android IDE. After I installed the Flutter and Dart plugin, there is no “New Flutter Project” option in IDE.
I search on the Google. I found this stackoverflow
# flutter upgrade
I run that command twice. At first time, it found two “Android Studio”. The lower version has not install the flutter plugin, so I remove it. At second time, I get following message:
