Display current git branch name in terminal or integrated terminal in VS code

step 1: create a file as .zshrc in Users/your_name/ directory and open it using TextEditor (note: no need to create if already exist)

step 2: paste the below code at the end of that file and save it

function git_branch_name()
{
  branch=$(git symbolic-ref HEAD 2> /dev/null | awk 'BEGIN{FS="/"} {print $NF}')
  if [[ $branch == "" ]];
  then
    :
  else
    echo ' %F{cyan}('$branch')%f'
  fi
}

setopt prompt_subst;

PS1="%K{default}%F{magenta}%B%1~%b%f"'$(git_branch_name)'"%k %# "

step 3: restart your terminal/integrated-terminal to see the changes

To customise the style
