React Native doesn’t include support for icons
so third party libraries are used.

In Flutter, importing the Material library also pulls in the
rich set of Material icons and colors.

When using the Icons class,
make sure to set uses-material-design: true in
the project’s pubspec.yaml file.
This ensures that the MaterialIcons font,
which displays the icons, is included in your app.
In general, if you intend to use the Material library,
you should include this line.

Flutter’s Cupertino (iOS-style) package provides high
fidelity widgets for the current iOS design language.
To use the CupertinoIcons font,
add a dependency for cupertino_icons in your project’s 
pubspec.yaml file.
