Do the following steps:
Download the Flutter SDK Flutter SDK Archive
Extract it where do you want (for example /home/development/flutter
)
Set your PATH, edit your file with this command gedit ~/.profile
, you need to add this line
export PATH=[location_where_you_extracted_flutter]/flutter/bin:$PATH
I showed you above where I've extracted mine, so my export will look like this
export PATH=/home/myUser/development/flutter/bin:$PATH
source ~/.profile
to load the changesflutter doctor
should work!
