Autofocused TextField in TabView Mode causes RangeError in Exchange Rate Screen

[rajput-hemant]

I encountered an issue with the app's TabView mode where, upon switching to the Exchange Rate screen, the autofocus feature of the TextField throws a RangeError if the TextField is not manually focused. The error message displayed is as follows:

RangeError (end): Invalid value: Not in inclusive range 0..1: -1.

Steps to Reproduce:

When TabView is enabled:

• Launch the app and navigate to the Settings screen.
• Ensure that the TabView is turned on (it is turned on by default).
• Go to the Exchange Rate screen.
• Start inputting data into the TextField.
• Observe that the input is not registered until the TextField is manually focused.

When TabView is disabled:

• Launch the app and navigate to the Settings screen.
• Turn off the TabView feature.
• Go to the Exchange Rate screen.
• Start inputting data into the TextField.
• Observe that the input is registered immediately without requiring manual focus.

Expected Behavior:

When in TabView Mode, the autofocused TextField in the Exchange Rate screen should accept input without requiring manual focus.

Please let me know if any further information is needed to investigate and resolve this issue. Thank you!
