In Android, Intent there are two main uses: for activity jumping between, and for communication between components. Flutter As there is no activity, fragmentthe component corresponding to the direct, but rather Navigator, Route to switch between the screens with which activity . Route is the abstraction of the application screen and page, but Navigator is a management Route control . It can be Route seen roughly activity, but they have different meanings. Switch the screen Navigator by push and pop(can be seen as pushing and popping) Route, and the Navigator working principle can be seen as a stack, which push means switching forward and pop returning. In Android, you need Android Manifest.xmlto declare activity, and in Flutter , you have the following page switching options: Specify a () containing all Route names Map MaterialApp void main() { Navigator.of(context).pushNamed('/b');
But in flutter there is no Intent such concept, although you can still start via local integration native integrations(using plugins ) Intent.

'/b': (BuildContext context) => MyPage(title: 'page B'),
'/c': (BuildContext context) => MyPage(title: 'page C'),
},
));
