not sure why is this code here and not inside _handlePaste

- The previous behaviour was not allowing users to override previous individual otp field. What I did here is basically made the field length to 2.
- When users want to paste otp they need to be on the initial field only and the text length should be equal to otp field length (Line number 215)
- if the length is less than or equal to 2, we assume user wants to override previously written text -> We remove replace previous digit from this text and set the text to newly written text (In case of previously its being 2, and user writes 0 -> we replace 2 with '' and set text as 0)
- if the same individual otp field doesn’t contain any text (i.e., user is typing first time) we handle it with line number 222's else block.
- I have added onTap() function to make sure, user stays in the end of otp field to handle back press efficiently. (Previously when the user's cursor was pointing before text, it didn’t allowed erasing the text and wasn’t taking back to previously available field)
