interface | allows dronekit control from python | Automation library

In my flutter project, I have made some updates of plugins and then used flutter upgrade. After that, whenever I am running my flutter project it is showing following error-

I'm new to Android development and I'm currently building my first real app. I'm trying to implement a MVVM architecture and because of that I'm having a viewModel for each fragment and each viewModel has a viewModelFactory. At least, this is how I understood it has to be.

I use the boilerplate code everyone seems to use for the factory:

I have updated my project to Xcode 13 and iOS 15. Now the app is crashing with an error related to autoresizing masks in UITableViewCells. I have tried to change UITableViewCells Layer property in the inspector to Inferred and followed this post, but none of them are working.

Have you encountered this problem. How it could be fixed?

Here is some information about the error:

I just installed react navigation version 6 and i received below error

Attempt to invoke interface method boolean com.swmansion.reanimated.layoutReanimation.NativeMethodsHolder.isLayoutAnimationEnabled() on a null object reference

below is my code

I'm looking for a way to have all keys / values pair of a nested object.

(For the autocomplete of MongoDB dot notation key / value type)

With Kotlin 1.5 was introduce the sealed interface. Even that I know the difference between classes and interfaces, I'm not clear what are the best practices and beneficies of using sealed interface over sealed class

Should I always use interface now even when is a simple case? Or will be a case by case?

Thanks

Obs: Didn't found similar questions, only about sealed classes

I'm having trouble getting my head around the purpose of supply {…} blocks/the on-demand supplies that they create.

Live supplies (that is, the types that come from a Supplier and get new values whenever that Supplier emits a value) make sense to me – they're a version of asynchronous streams that I can use to broadcast a message from one or more senders to one or more receivers. It's easy to see use cases for responding to a live stream of messages: I might want to take an action every time I get a UI event from a GUI interface, or every time a chat application broadcasts that it has received a new message.

But on-demand supplies don't make a similar amount of sense. The docs say that

An on-demand broadcast is like Netflix: everyone who starts streaming a movie (taps a supply), always starts it from the beginning (gets all the values), regardless of how many people are watching it right now.

Ok, fair enough. But why/when would I want those semantics?

The examples also leave me scratching my head a bit. The Concurancy page currently provides three examples of a supply block, but two of them just emit the values from a for loop. The third is a bit more detailed:

It seems to me that Pandas ExtensionArrays would be one of the cases where a simple example to get one started would really help. However, I have not found a simple enough example anywhere.

To create an ExtensionArray, you need to

• Create an ExtensionDtype and register it
• Create an ExtensionArray by implementing the required methods.

There is also a section in the Pandas documentation with a brief overview.

There are many examples of implementations:

• Pandas' own internal extension arrays
• Geopandas' GeometryArray
• Pandas documentation has a list of projects with extension data types
  • e.g. CyberPandas' IPArray
• Many others around the web, for example Fletcher's StringSupportingExtensionArray

Despite having studied all of the above, I still find extension arrays difficult to understand. All of the examples have a lot of specifics and custom functionality that makes it difficult to work out what is actually necessary. I suspect many have faced a similar problem.

I am thus asking for a simple and minimal example of a working ExtensionArray. The class should pass all the tests Pandas have provided to check that the ExtensionArray behaves as expected. I've provided an example implementation of the tests below.

To have a concrete example, let's say I want to extend ExtensionArray to obtain an integer array that is able to hold NA values. That is essentially IntegerArray, but stripped of any actual functionality beyond the basics of ExtensionArray.

I have used the following fixtures & tests to test the validity of the solution. These are based on the directions in the Pandas documentation

The Function Interface is introduced in Java 8, to implement functional programming in Java. It represents a function that takes in one argument and produces a result. It's easy to practise and read, but I am still trying to understand the benefit of it other than just making it look cool. For example,
