[Question]: edit previous entered value

[jvinai]

Hi,

Im using the PinCodeTextField with a lenght of 6.
If i enter 4 first numbers but want to change the first value by tapping on the first input, i cant.

1 2 3 4 - -
Taping on 1, it will put the focus on the first empty value.
The only possibility to edit this 1 is to remove the all previous values.

Is this the expected behavior or a bug?
Is there an option to allow the edition of previous values i missed while reading the doc?

Thank you!
