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 trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

I figured out that these lines in our build.gradle file are the origin of the problem.

A Flutter Android app I developed suddenly compiled wrong today.

Error:

when I run android application in real device I am getting following gradle errors

I've built my React Native app and tested and troubleshooted with my iOS devices for months. Now I'm trying to built and test the app on Android for the first time. The thing is, that I keep getting errors trying to run the Android-version of my app. After hours of debugging and troubleshooting, I tried to create a new RN project and see if that could run on my emulator and device. I got that part working and then I wanted to copy/paste the files of my existing app project into the new project.

I pasted my existing assets, styles, the source JS-files and the package.json file into the new project, ran npm install and then I ended up with the exact same error message as I had in the original project when I run react-native run-android.

The full error message is here:

I just updated flutter version from 2.5.3 to 2.8. I have the following error that i dont know how resolve it. There is no error on any plugin installed, It seems that the error comes from the inner classes themselves and I don't know in which part of my application the error is throwed:

I have created a new flutter project and added camera plugin. after adding that dependency I got many errors. I used futter version is 2.5.2 & minSdkVersion 21

In pubspec.yaml file,

I need an ArgumentParser, with a conflict handling scheme, that resolves some registered set of duplicate arguments, but raises on all other arguments.

My initial approach (see also the code example at the bottom) was to subclass ArgumentParser, add a _handle_conflict_custom method, and then instantiate the subclass with ArgumentParser(conflict_handler='custom'), thinking that the _get_handler method would pick it up.

This raises an error, because the ArgumentParser inherits from _ActionsContainer, which provides the _get_handler and the _handle_conflict_{strategy} methods, and then internally instantiates an _ArgumentGroup (that also inherits from _ActionsContainer), which in turn doesn't know about the newly defined method on ArgumentParser and thus fails to get the custom handler.

Overriding the _get_handler method is not feasible for the same reasons.

I have created a (rudimentary) class diagram illustrating the relationships, and therefore hopefully the problem in subclassing ArgumentParser to achieve what I want.

I (think, that I) need this, because I have two scripts, that handle distinct parts of a workflow, and I would like to be able to use those separately as scripts, but also have one script, that imports the methods of both of these scripts, and does everything in one go.

This script should support all the options of the two individual scripts, but I don't want to duplicate the (extensive) argument definitions, so that I would have to make changes in multiple places.
This is easily solved by importing the ArgumentParsers of the (part) scripts and using them as parents, like so combined_parser = ArgumentParser(parents=[arg_parser1, arg_parser2]).

In the scripts I have duplicate options, e.g. for the work directory, so I need to resolve those conflicts.
This could also be done, with conflict_handler='resolve'.

But because there are a lot of possible arguments (which is not up to our team, because we have to maintain compatibility), I also want the script to raise an error if something gets defined that causes a conflict, but hasn't been explicitly allowed to do so, instead of quietly overriding the other flag, potentially causing unwanted behavior.

Other suggestions to achieve these goals (keeping both scripts separate, enabling use of one script that wraps both, avoiding code duplication and raising on unexpected duplicates) are welcome.

I have tried to build app 'flutter_html: ^2.1.5" but I unable to build and getting below error in log.
