Why do I get this bash error? "export: `/home/atul/Public/Android': not a valid identifier."

I did this from the ~ directory.

I typed this command
sudo gedit .bashrc

then I appended these lines to the file and saved it.

#Adding flutter and android path
export ANDROID= "$HOME/Public/Android"
export FLUTTER= "$ANDROID/flutter"
export PATH= "$PATH:$FLUTTER/bin"

Now when I open the terminal I get the following error:

bash: export: `/home/atul/Public/Android': not a valid identifier
bash: export: `/flutter': not a valid identifier
bash: export: `/home/atul/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/bin': not a valid identifier
atul@mintMate:~$ 

Its good that I have fish installed else I wouldn’t have been able to
use the terminal.
Please help me solve this error.

>Solution :

You cannot have a space after the = in your assignments. Change them to this.

export ANDROID="$HOME/Public/Android"
export FLUTTER="$ANDROID/flutter"
export PATH="$PATH:$FLUTTER/bin"
