Developing a Dart Flutter app. I need to validate if an English word that the user inputted is in the dictionary or not.
Is there a package or API interface to Wordnet or similar dictionary?
Is it possible to get from the dictionary of word is verb, adjective or noun?
First of all you will have to find an API, if you find one, then you will have to communicate with it by using the 'http' package of Flutter and by creating your implementation.
If no API is available and I think it is the case (I'm not 100% sure), then you have two options.
The first one is to create a scraper for the dictionaries or the website, you can use the WordNet web interface(http://wordnetweb.princeton.edu/perl/webwn) and use the web_scraper plugin to try to access and retrieve the data (make sure you have the rights to do so).
The second option (for me the best), is to create your own API knowing that WordNet offers to download their database file under license.(https://wordnet.princeton.edu/download)
You can use a web framework(Express.Js https://expressjs.com/fr/ is quite simple) depending on the language you use to create your api rest using the WordNet database file or by creating a database with this file.
Clearly, it's complicated but not impossible, the last option is the most complex and the first one is rather unstable...
I specify that this answer is only my opinion and maybe there is another solution, if yes I let then other person answer.

I am trying Flutter in a small App for my company. I come from the C# world.
My Scenario
I get data from a server (json). The objects (possibly thousands of them) i get can have any number/type of properties, which are only known at runtime.
What am i looking for?
Basically i am looking for an alternative to C#'s DataSet in Flutter.
About DataSet the documentation says:
is an in-memory cache of data retrieved from a data source
What do i have so far?
I have looked through the web without finding anything that answers my question. The only approach i came up with was using a Map-like approach to store the json items, but i hope there is something else in Dart i can use since C# also has Dictionary, but DataSet is very rich compared to it, see the docu on DataSet...
NOTE: In C# i used to use also a Reflection-Emit approach to crate classes at runtime once i got the data, but since i am also developing for iOS, that approach is not allowed (JIT not allowed)
I made a json api with using this => https://www.django-rest-framework.org/tutorial/quickstart/
All the articles I read teach the creation and use of api within its own platform, what I need is what I produce on the web, use it to in other platforms. I made my api but no idea about how to import it in other platforms..
so how can I use my own api in my c# windows form application or my flutter project
Any link, guide etc.
First of all you should be clear about why you need an api. If you need to transfer data from one system to another, pick a way that you know you can operate on both sides.
JSON or XML are just ways of representing data, first think about what you need and how can you transport that data between systems...After that the implementation should be clear.
I'm new to flutter/dart and I'm trying to create a little application using a Clean Architecture design.
I read some blogs and several presentations of Uncle Bob's Clean Architecture before starting to code to get the most of it and now it's time to implement it.
I guess my application could be divided in 3 main features :
authentication
classes (get access to lessons/quizzes on specific subjects)
admin (manage user, create lessons etc..)
I started to implement the authentication feature following the clean pattern, that's to say with a domain, data and presentation layer and I guess I did it quite well. It's (almost) fully tested (I'm trying to do some TDD) and seems to work as I wanted.
Now comes the problem. I want to implement the classes feature. I wish it could be independent of the authentication but it's not the case... The classes feature need to get the authenticated user from the authentication feature. I searched a lot on the internet but I can't find how to implement Clean Architecture with multiple features that need to share some data.
So there are my 2 questions:
How to pass data from a feature to another ?
How to inject dependency in a feature that need data from another feature ? (I used get_it for the authentication feature and inject all dependencies in the main() method before building the app. Since it did not need any external data it worked well. Now it's seem not possible to do the same for the classes feature since it first needs to get some data from the authentication feature).
Thanks in advance for your answers.
Along with your 3 features you should add another called core and inside that folder you can add stuffs that need to be shared. It worked for me . Good luck
One option is if you instantiate classes after the user has already logged in, you can pass that data in as a constructor parameter.
More generally, Provider is probably the best dependency injection tool for flutter. If you "provide" the authentication class to the widget tree for the rest of the app, you can say at any point below it, Provider.of(context) to access it and any public field it has.
Hope you're still working on Flutter projects after that long time.
I've been fiddling around with Uncle Bob's Clean architecture, and I managed to implement it in Flutter few months ago.
It's perfect, it separates your code into components (modules if you're coming from a native Android development environment) and isolates your data sources, so if you want to change the way you make API requests for example, you'll only need to change the remote data source part in your app, and all your application should work as expected.
I have made a test app using Clean Architecture I just uploaded on github and added a humble readme that describes the basic architecture and components of the app, I'll work on written articles describing the code very soon.
For now you can access the repo from here
I'm trying to find an answer to this for some time now... My solution was to create some transformation methods in the model class. For example, I have an ProductModel in the home feature file (from where i can add products to the cart), and an ProductInOrderHistoryModel in the order history feature file. So in the ProductInOrderHistoryModel file I have a method called toProductModel that gets an instance of ProductInOrderHistoryModel and transform to a ProductModel. That way I can add a product to the cart directly from my history order page.
Probably it's not the best solution, and the Uncle Bom would be really mad at me. But it was how I manage to solve my problem...
I've looked around the site to see if there are any people who have changed the CKAN API interface so that instead of uploading documents and databases, they can directly type onto the site, but I haven't found any use cases.
Currently, we have a page where people upload data sets through excel forms that they've filled out, but we want to make it a bit more user friendly by changing the API so that they can fill out a form on the page rather than downloading the template, filling it out and then uploading it.
Does CKAN have the ability to support this? If so, are there any examples or use cases of websites that have use forms rather than uploads?
This is certainly possible.
I'm not aware of any existing extensions that provide that functionality, but you can check the official list of CKAN extensions if there's anything that fulfills your needs.
If there is no existing extension that suits you then you could write your own, see the extension guide for details on how to do that.
Adding an API function to CKAN's API is possible, but probably not what you want in this case: the web UI usually does not interact with CKAN via the API but via Flask/Pylons controllers. Hence, you would add your add controller which first serves your form and then processes the submitted inputs.
You can take a look at the ckanext-pages extension, which does exactly that (for editing static pages instead of datasets, but your code would be similar).
I'm currently using the Jira SOAP interface within a C# (I suppose the language used here isn't terribly important).
Basically, I'm creating an API and a Winform that wraps some of the functionality of the soap service so that our Devs can programmaticly add bugs when something goes wrong in our application.
As part of this, I need to know the custom field IDs that are in use in Jira, rather than hardcoding them (as they are still prone to the occasional change) I used the GetCustomFields() method in the jira-rpc api then filtered it, so that all the developer needs to know is the name of the field, then the ID is filled in for them automagically.
This all works fine, but with one quite important proviso: that you login to the SOAP/RPC service as a user with administrative privaliges.
The Jira documentation indicates that the soap/rpc service follows the usual workflows and security schemes, however I can't find anything anywhere that would appear to remove this restriction on enumerating custom fields (and quite why in any instance you would want someone to HAVE to be an administrator to gain this access, especially as the custom field id's tend to be in Jira's HTML source is beyond me)
Does anyone know if I've missed a setting somewhere? Or if there is some sort of work-around for this, short of hardcoding the custom field id's?
Or is this a case of having to delve in to Jira's RPC plugin and modifying the source for it in order to give me the functionality I require?
Cheers
Edit for the sake of google/posterity
Wow, all this time on, and it looks like Atlassian still haven't changed this behavior.
Worked around this by creating a custom dictionary that logs in as an administrative user, grabs the custom fields and then logs out. Not ideal, but it should work 'til atlassian change things
You're not missing anything - there's no way to get custom fields via standard SOAP API.
In JIRA Client, we learn about custom fields in two ways:
We download issues via RSS view of the issue navigator, or via XML representation of a specific issue. If a custom field is set for an issue, the XML will have its id, class and value (values).
From time to time we inspect the content of IssueNavigator search page - looking for searchers for the custom fields. Screen-scraping the HTML gives us not only ids of the custom fields but also possible values for enum fields.
This is hackery, of course, and it may go wrong, so a good API would have been a lot better.
In your case, I can suggest two solutions:
Create your own SOAP (or REST) remote API plugin that will give you just that info that you miss from the standard API. Since you're seemingly in control of your JIRA, you can install anything there.
Screen-scrape the "New Bug" page for the project and type of issue you need to submit. You'll get all the info - fields, options, default values, which field is required.
