Number Picker Dynamic live

Usage

NumberPickerDynamic only require option onValueChange callback to be set.

onValueChange returns the current value of the number picker.

NumberPickerDynamic(
  height: 100,
  maxDecimals: 5,
  initValue: 100,
  onValueChange: (value) {
    debugPrint("Value is $value");
  },
),

Design is based on the height value and the "bend" you want the dial to be. If you lower the height bending numbers could make things fit. Do remember to test on different devices and screen sizes.

Additional information

Note that TextScale is locked to 40%. Values above this makes things clip.
