@CloudyPadmal Thanks you I try it last night and I'll fix the squashed.

It is squashed already. May be you didn't see that there's only one commit.

[MohitGupta121]

No, I squashed it at night with lots of efforts, there is 16 commits when I'll make pull request.

But I'm its really good to seee the squashed commit and clean PR.
Anyways Now I understand how to squashed.
