Flutter: Popandpushnamed With Arguments Passing To New Page?

I am writing an application on Flutter. I need to do popAndPushNamed but I also need to pass arguments to the Page I am pushing. How can I do? Is there another way to pop and push

Solution 1:

For sending data to widget you can use it's constructor

String result = awaitNavigator.of(context).push(MaterialPageRoute(builder: (context) =>SecondWidget("String")));

In this case result is new string, which will be returned from SecondWidget

classSecondWidgetextendsStatefulWidget {
  SecondWidget(this.text);
  final String text;

And somewhere in SecondWidgetState:

Navigator.pop(context, "New string");

This will close SecondWidget and return value for result I think it's clear enough and it'll help

UPD How to do in your case (something like this)

Profile profile = awaitNavigator.of(context).push(MaterialPageRoute(builder: (context) =>LoginWidget()));
if (profile != null) Navigator.of(context).push(MaterialPageRoute(builder: (context) =>MainWidget(profile)));

In LoginWidget:

void_afterLogIn() {
  // do somethingNavigator.pop(context, this.receivedProfile);
}

In MainWidget:

classMainWidgetextendsStatefulWidget {
  MainWidget(this.profile);
  Profile profile;
