Multiple navigators in Flutter causes problem with pop

生来就可爱ヽ(ⅴ<●) 提交于 2021-02-20 04:12:27
问题 I'm struggling in a Flutter situation with multiple navigators. Concept here is a page which triggers a modal with his own flow of multiple pages. Inside the modal everything is going swiftly (navigation pushes/pops are working), but if the modal is dismissed it removes every page of the lowest navigator. I've looked at the example of https://stackoverflow.com/a/51589338, but I'm probably missing something here. There's a wrapper Widget inside a page which is the root of the application.

问题 I have a class that has to take a custom widget. This one can have two different implementations, so I would like to have an abstract class as interface and create two other classes those extend the abstract one. So, I have: abstract class ICustomWidget extends StatelessWidget{} class A extends ICustomWidget{ @override Widget build(BuildContext context) => //Implementation } class B extends ICustomWidget { @override Widget build(BuildContext context) => //Implementation } I want to ask if

问题 I'm running a jupyter notebook but the jupyter widgets does not appear. Instead I receive the folllowing message: Failed to display Jupyter Widget of type Button. If you're reading this message in the Jupyter Notebook or JupyterLab Notebook, it may mean that the widgets JavaScript is still loading. If this message persists, it likely means that the widgets JavaScript library is either not installed or not enabled. See the Jupyter Widgets Documentation for setup instructions. If you're reading
