Fix Font issue

[S-Man42]

(At least on web building)

Expected to find fonts for (MaterialIcons, MyFlutterApp, packages/cupertino_icons/CupertinoIcons), but found (MaterialIcons, MyFlutterApp). This usually means you are referring to font families in an IconData class but not including them in the assets section of
your pubspec.yaml, are missing the package that would include them, or are missing "uses-material-design: true". Font asset "MyFlutterApp.ttf" was tree-shaken, reducing it from 1784 to 828 bytes (53.6% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when building your app. Font asset "MaterialIcons-Regular.otf" was tree-shaken, reducing it from 1645184 to 16972 bytes (99.0% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when building your app.
