无法执行Flutter Doctor命令

Question

I wanted to explore flutter and followed this link for installation steps. I added the path and checked it with echo $PATH and I see the flutter files in that path. After I execute flutter doctor in my terminal, I get the following error:

dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib
  Referenced from: /usr/local/bin/bash
  Reason: image not found
Abort trap: 6

I executed flutter doctor inside flutter's image folder / working directory only. I googled for the error and I tried the following:

1. brew upgrade bash
2. ln -s /usr/local/opt/readline/lib/libreadline.7.dylib /usr/local/opt/readline/lib/libreadline.6.dyli
3. brew link readline --force

but I still face the same issue.

I tried the following and I got the result:

1. MacMini3:flutter deepakt$ brew install bash

Updating Homebrew... Warning: bash 5.0.0 is already installed, it's just not linked You can use brew link bash to link this version.

2. MacMini3:flutter deepakt$ brew link bash

Linking /usr/local/Cellar/bash/5.0.0... Error: Could not symlink bin/bash Target /usr/local/bin/bash is a symlink belonging to bash. You can unlink it: brew unlink bash

To force the link and overwrite all conflicting files: brew link --overwrite bash

To list all files that would be deleted: brew link --overwrite --dry-run bash

3. MacMini3:flutter deepakt$ brew unlink bash
