How to add hint, tooltip for tell user?

[SittiphanSittisak]

Most users don't know how to change the year.
Can you add something looks like this?

Add some properties like

• tooltipYearMessage: "Hi, change the year here!"
• tooltipYearTextStyle: TextStyle()
• tooltipBackground: Colors.transparent
  Or just
• tooltipYearWidget: Widget()
  and this
• tooltipAutoPlay: true
• tooltipDuration: Duration(seconds: 3)

It will be better if you add a property like helperWidget: someWidget()

It can help. We can add a widget to show any hint or anything that users want.
