Flutter has a cached version of the app on the device . Run

flutter clean

in your app directory.

OR check whether material icon dependency is in pubspec.yaml or not:

flutter:
uses-material-design: true

CodePudding user response：

There is no icons for "currency_ruble". Currencuy_ruble is not of type IconData. That's why it's showing error. If you want to use custom icon then use that icon by using Image.asset() if currency_ruble is of type image or SvgPicture.asset() if it's of type .svg

IconButton(onPressed: onPressed, icon: Image.asset("<image file name>"))
