ColorScheme | A color scheme

I am using Flutters TimePicker to allow user to select a time.

This uses the TimeOfDay Class.

I need to the selection in RFC 3339 format (2022-06-24T01:23:45)

Is there a way to convert it or do I need another package to select instead?

I know that there is a date parameter in there too and the current day would be what I want to insert, not sure of this can be auto populated with current date?

When I try to convert it with a function I receive

I am working on flutter a flutter project and using MaterialApp while providing the ColorScheme I used primaryVariant property but now Official documentation is saying that it is deprecated and asks to use primaryContainer. But I could not find any reasons for that what was wrong with primaryVariant? Why has it been deprecated?

I am trying to render certain nav stacks depending on a isAuthenticated state. The problem that I am having is that AppNavigator is only rendered on the first render and not with any other changes and I am not sure why. I have tried a useEffect in the AppNavigator component to set a secondary local state with the callback being isAuthenticated but no go. I put everything pertinent below. I appreciate any advice.

I have an AppNavigator that is being rendered in my app.tsx file.

I'm getting this error:

I'm writing a flutter application and I'm trying to define my own themes for light and dark themes. coding with android studio and testing it using the regular android emulator that comes with it.

I've got a ReorderableListView where the ListTile contains a Slider() widget. If I don't touch any of the Slider() widgets, I can reorder the ListTiles with no issue. But, as soon as you click-on or interact with any of the Slider() widgets, then attempting to reorder the items throws() with this error in the debug console (many of them):

I am currently developing an iOS widget with SwiftUI and have a strange behaviour of the background-image of my medium-sized widget.

I am setting a background-image depending on the current color mode of the device, which works most of the time. But when the app is in the background for a couple of minutes, the background-image goes black, which makes the text unreadable. Any other UI-elements are still visible. When I resume to my app, the widget refreshes itself and the background-image is visible again.

The background-images are included in my image.assets of my widget-extension, so it should be always accessible for the widget, shouldn’t it?

This widget is available for iOS 14 and above.

This is how I set the background-image:

In official Material Design 3 resources (e.g. the Figma design kit), there have been many references to colors called "Surface at +x". These colors are the surface color mixed with x% of the primary color.

Now my question:

How can you implement the "Surface at +x" colors in Jetpack Compose? There is no documentation and no property on the MaterialTheme.colorScheme object.

I'm getting odd behavior using @reach/router My aim is to have a page with tabs. When I click on a tab the url changes and the page changes (though it doesn't reload the whole page). I've been using chakra ui since it makes the theme making easier for me.

The behavior i get is odd. Sometimes the url changes as I switch between tabs. It works great. Then sometimes the url dosen't change, even though I've switched tabs.
