Use case

When a user needs to input a date in the distance past or future (such as a birth date), the material design guidelines recommend using a mobile date input picker. The showDatePicker() method in flutter does not support this type of picker.

I cannot find a flutter library implementing this.

Proposal

Add a material widget implementing the mobile date input picker show in the material design guidelines: https://material.io/components/pickers/#mobile-pickers.
