Use flutter run from the project’s root directory.

Your app runs on a connected device, the iOS simulator,
or the Android emulator.

For more information, see the Flutter Getting started
documentation.

How do I import widgets?

In React Native, you need to import each required component.

// React Native

import

React

from

react

import

StyleSheet

Text

View

from

react-native

In Flutter, to use widgets from the Material Design library,
import the material.dart package. To use iOS style widgets,
import the Cupertino library. To use a more basic widget set,
import the Widgets library.
Or, you can write your own widget library and import that.
