Hi @siinghd,

This PR disables the login button when there is no input in either of the fields
I have added an useState variable to catch the input field entries and used the same for disabling/enabling the button
There is no change in the login functionality

As of now when I am creating this PR, there is only 1 PR other than mine which also addresses the same issue - #866
I went through its implementation, it has addressed the issue using toaster so I decided to create another PR which will address the same issue using Login button.

Thanks

PR.mp4

I have a couple of things to say,

• I have changed only 1 file Signin.tsx, other files came for formatting
• the format check is failing in this PR, each time I run yarn format:fix, format issue fixes locally, but while commiting, that change reverts automatically, I don't know why this is happening.

To make the component controlled I have used 2 useState() variables, I have tested code from my end.

Thanks
