2. Enhanced _onTextChanged Logic #

• Redirects input to last empty controller before current index.
• Supports multiple character input (pasting or fast typing) by splitting input across fields.
• Automatically moves focus forward or backward based on input or deletion.
• Calls _handleOnComplete() to detect when OTP input is complete.

3. Updated _onBackButtonClick Behavior #

• Removes clearing previous field’s text on backspace; now only shifts focus backward.
• Improves natural keyboard navigation and input correction.
