I get this error when I try to use FixedExtentScrollController, I use it to create timers choosing the day with this controller,
When I start the application everything works correctly, I can choose the day well and create my timer, but when I go back to the timer creation page and try to move the controller to choose a new day I get this error. I don't know what it could be, since it used to work fine, and the last thing I did was update to flutter 2.5. Surely I can change the method I use to select the days for another but I liked it that way. If someone could help me, since the problem does not make me very clear what it can be, he tells me that it is my FixedExtentScrollController, but I do not understand why.
