Flutter raised button

A Raised button is based on a Material widget whose Material . elevation increases when the button is pressed. Use raised buttons to add dimension to otherwise mostly flat layouts, e.g. in long busy lists of content, or in wide spaces. Avoid using raised buttons on already-raised content such as dialogs or cards.19 Nis 2018

In Flutter, RaisedButton widget is a material design concept of a button with elevation . It provides dimensionality to your UI along z-axis with clues of shadow. RaisedButton is depreciated.

The solution is adding onPressed() property to RaisedButton. Because, if onPressed() property is not provided, even with the empty function, RaisedButton is considered as disabled .
