As I see several dart packages published at dart package website, I am curious to know what packages does flutter endorse?
The question would be vague, so I would like to focus on a specific package dio. I have contacted few flutter developers, and have been told that the package is not yet a industry standard, also I was introduced to some packages that were published just hours back, for example jaguar_retrofit. I also see dart https package used frequently in flutter documentation.
This weighs me to look at what would be the most promising in the future.
Can someone solve the package mystery for me, any flutter insights available?
This is a valid question, but not one that you'll probably find a final answer to on stackoverflow (and it may be closed as off-topic although I won't cast that vote). You might find better luck at https://softwarerecs.stackexchange.com/ although there may not be too many dart/flutter specific people there; I don't know for sure.
But realistically, no-one knows what might happen to the packages in the future other than the people maintaining them. That would probably be a good first step - make contact with the developers as they will be able to give you a better indication of how committed to maintaining their code they are.
Other than that, what I'd look for is who the publisher of the package is (see below, under the "Author").
If it is the 'Dart Team' or 'Flutter Team', there's a fairly good chance it will be maintained. If it isn't, but the uploader has a '#google.com' email address, there's a chance it's just one of their 20% projects, but there's still a better chance of it being maintained than a random dev.
And finally, if the package's licence allows for it (which pretty much everything on pub should) you may be able to help the developer with it in the future, in which case everyone wins =).
It helps to look at the official documentation:
Fetch data from the internet
JSON and serialization
More in the cookbook.
Some time ago, I took a look at the dio source code and I'm not really convinced that it is a good option. Basically it is just a thin wrapper around the standard http library.
The retrofit clone seems to rely on a custom JSON serializer code generator, instead of using one of the standard solutions.
A non-technical question
I have been helped by a few folks (here on SO) with my questions and would like to acknowledge them in my package.
How can I do that, should I add them with ctb (contributor) role, or is there another role available for people who might not have provided actual code/content but have helped in tackling issues.
Thanks
I am trying to run a LINQ query within a website plugin with Dynamics CRM Hosted. I need to us LINQ to retrieve a list of all the currently registered Members as shown in the MemberWorks tab. But to be host I have no idea where to start.
Ive really jumped in at the deep end with this one to help out a friend, and I find that necessity and crushing time demands are the best way to challenge my brain and learn something new. So please if you van give me relevant pointer Id really appreciate it.
To clarify my LINQ knowledge is at beginner level and my knowledge of the hosted Dynamics CRM datastructure is at a similar level. So Ive not really tried anything as I simply don't know where to start at this stage. But hopefully some kind folk can give me direction and Ill see where that takes me.
Thanks in advance!
If you look at Hosk's blog you will probably find your answer, if not you will have other questions to ask :)
It's quite hard to give an answer to a question this general so excuse me if it's a bit fuzzy and not exactly what you expected
I have an application I would like built. For the most part, I know what I want. And, I have good sketches of how it should work and look.
I would like to understand how to estimate the cost to implement an application. I would like to do this prior to approaching developers so that I can make sure I can afford to fund the development myself and not waste anyone's time.
I can imagine that this is not an easy question to answer, and perhaps one that can't be answered here at all. However, I'm hoping there are some ballpark figures and methods to approximate cost.
Also, If anyone has any suggested steps to going from idea to implementation, I'd love to hear them. Thanks!
Clarification: I'm not looking for an answer with a dollar amount. I'm looking for guidance on how to come up with a (very rough) figure. Ultimately, I'll be using this figure to determine whether or not I can comfortably fund development personally. Again, this question may be flawed, but I can't help but think that someone might have a savvy answer. Perhaps a figure of cost/time based on a project of their own or good advice otherwise. Just don't tell me it'll cost a million, because Robert already has. :)
To be honest, if the project is in the middle ground where you may or may not be able to fund it personally, I'd say err on the side of caution. Too often, a project that should be able to be completed in a certain amount of time drags on. That can be the result of a mistaken estimate or because of opportunities that open up in the project that expand the scope. The worst thing I've seen happen to a promising project is that it runs out of funding just as it start to build steam.
You say you have good sketches of how it should work and look. Get that together with some text describing EVERYTHING about the app. Now you can post that for bids on Elance and ODesk or wherever (those are just two that come to mind). The more detail you have, the better it is.
Get some quotes is the only way to know really.
It also depends on what you are getting as a product ... the source? it hosted?
Some web-firms that will also host your app have in-house CMS and work systems to get things done cheaper/faster. This doesn't mean they will pass the cost back however.
Cheapest, also isn't best. You need to set a budget and get the most for it.

I love working with Rails but I keep tripping up against my own inefficiency: I'll spend time implementing some "useful" function only to discover subsequently that it was already in the framework, had I but known it!
Particular areas of wheel reinvention for me are
helpers and built-in class extensions
recently-released features that may not yet have lodged in my brain
plugins (a taxonomy of Rails plugins, if such a thing makes sense, would be a boon)
migration options
less-frequently used rake tasks
the options hash on just about everything
Obviously (?) we can't all remember all this stuff all the time. There are "cheat sheets", but unless they're up-to-date they can potentially compound the problem by appearing authoritative when they're really targeted at older versions.
What do you do to minimize this excise? Can anything be done?
I wondered if a set of Big Visible Charts might help, although goodness knows where I'd stick them in an open-plan office.
One thing here is to know about the existence of particular feature (plugin, gem, etc) in the first place. That's why
I try to keep up to date with the information about the edge Rails.
I follow many blogs and try to if nothing else then run over the titles every day, just to have it leave at least some tiny footprint in my memory.
That's for the passive part. Now for the active:
As I fly through the new features/plugins I try to imagine at least some use case in which it might be helpful in what am I working on right now - this exercise helps me to remember the thing, since I connect it to my actual conceptual system.
In my less serious projects I really try experiment with new things.
On SO I often answer questions I'm not sure about or I don't really know anything about but they seem interesting to me - then I do some research and extend my knowledge on that particular topic.
I don't think that "big visible charts" can help in the long run. I only use cheat sheets when learning new things and it's really only a short term thing. Exellence is a habit, as Aristotle said.
This isn't just a problem with Rails, but with any framework. Programmers I know who have worked for years with Delphi still are shocked to find simple standard functions that they'd replicated.
WRT Rails, Mike Gunderloy recently wrote about highlighting text, and ended with this wise tidbit:
It’s worth taking a dip into ActionView::Helpers occasionally to see what other bits of functionality are lurking that you’ve forgotten about.
Any time I need to do something I think should be easier than it is, I do a quick check there, as well as Google, to make sure I'm not about to waste a ton of time.
I face this problem as well- and it was a lot worse when I first started with RoR. Now after over 1.5 years, I know what's available pretty well.
Basically what I do is if I am using parts of the framework I know... no big deal. If I need to do something I will likely have to create myself, I first google it or search the Rails API. Lately I have also begun searching github and some of the plugin sites like railslodge.com.
While this does not completely solve the problem, it has helped dramatically.
I surf over the rails blogs in my RSS feed reading the headlines and just enough to figure out what the article is about. This gives me a good breadth of knowledge but pretty shallow. Still it lets me know what is out there. Like yesterday when I saw a blog post about a highlight helper (I had no idea it existed. Now I do and if I ever need it I know to look for it - even without reading the post in depth). I also open the posts I want read in depth in another tab for later (I used to use ReadItLater but it got out of hand) and as i read them i write notes in a post on my own blog more for my own benefit than for others - to get into memory and to ensure I can find it later.
The other thing I do when I am entering uncharted or forgotten territory is to I ask a question here about best practices or specific details even if I think I know the answer. For example I couldn't remember the names of the popular plugins for tracking edit histories of records (acts_as_audited and acts_as_versioned). I had the answer in 15 minutes.
It turns solo programming into programming in one of those cool noisy dev shops with a foosball table and lots of other people who know stuff i don't.
I tend to assume that most types of basic problems I'm solving have already been solved by someone else; by starting with the assumption my thoughts aren't along the lines of "how do I build this" but "where do I find it" and of course google, the wikis and the plugin and gems lists all play a part in that. I have written very little code that isn't directly related to my business domain.
I write tests first. Then code. Sometimes the framework does it for me and I don't have to write code. :)
I don't think Rails is any different than other frameworks... it takes a while to know where things are. The best you can do is read the API docs and see what's there. You don't need to learn how to use it, just what is there and get an idea of how to look for it when you need it.
Also, it's not a bad thing to write code that someone else already has. You learn from it. Later you just swap in the framework mojo and see if your tests still pass. If so, you're good and you know how the internals of one part of the framework probably work.
I believe the key to eliminate the time wasted on reinventing the wheel is to have a very handful tool to search inside the Rails helpers/capabilities.
On one hand a good choice of IDE could help a lot. On the other hand - a very good online (offline) edge documentation with an ability to quick search through it. These days one of our russian Rails programmers made one: http://railsapi.com/. The search is done in a very MacOS style, making it a very good choice for a fast diggin'.
