6. 6. Achieving Flutter Setup

   Now to Complete Flutter Setup
   First, try to Accept the Licenses:

   flutter doctor --android-licenses

   In case of Issue, Update your Android Setup:

   touch ~/.android/repositories.cfg

   sdkmanager --update

   And again:

   sdkmanager --install --sdk_root=~/Android/Sdk "cmdline-tools;latest"

   Currently you are further bound to make a very Questionable??? Trick:

   mkdir $ANDROID_HOME/cmdline-tools/latest

   mv $ANDROID_HOME/cmdline-tools/* $ANDROID_HOME/cmdline-tools/latest

   And so consequently, if needed amend also the User’s PATH with Sed:

   sed -i "s/cmdline-tools\/bin/cmdline-tools\/latest\/bin/g" ~/.bashrc

   Without the latest one easily you be unable to Agree to the Licenses…

   And now, if you still miss it, see: How to Install Install Google-Chrome!

   Last, Congrats your Setup should be successfully achieved:

   flutter doctor
