NumberPicker

NumberPicker is a custom widget designed for choosing an integer or decimal number by scrolling spinners.

It is possible to use NumberPicker as a standalone widget as well as in NumberPickerDialog.

Getting Started

Creating NumberPicker Widget

new NumberPicker.integer(
                initialValue: 50,
                minValue: 0,
                maxValue: 100,
                onChanged: _handleChange)

Creating NumberPickerDialog (use in material's showDialog method)

new NumberPickerDialog.decimal(
          minValue: 1,
          maxValue: 10,
          initialDoubleValue: _currentPrice),

                onChanged: (newValue) =>
                    setState(() => _currentValue = newValue)),
            new Text("Current number: $_currentValue"),
          ],
        ),
