Tighten up you type checking in preparation of NNBD
If you already use

implicit-casts: false implicit-dynamic: false 

you will learn nothing new from reading this.Did you ever write something like

List<int> filterEven(List<int> ints){ return ints.where((item) => item % 2 == 0)); } 

which compiles fine, only to get a runtime error, and were annoyed that the Iterable got implicitly downcasted to List by the dart compiler, even though that will fail at runtime?There is a setting that turns this implicit downcasts off. Just add

analyzer: exclude: [build/**, lib/**/*.g.dart] strong-mode: implicit-casts: false 

To your analysis_options.yaml. This will be the default setting once NNBD is released (Source), so I really recommend turning this on.You might have to do some minor changes to your project, but nothing too bad.While you're at it, you also might want to add

implicit-dynamic: false 

to your analysis_options.yaml.This stops the type-inferrer from inferring dynamic, except when you specify the type dynamic explicitly. I strongly recommend turning this on, too. An implicitly inferred dynamic can cause really strange behavior, for example in this case:https://dartpad.dev/b42203ba5d7d8e5ff55f99bd003a81bfThe programmer forgot to add the generic type to the "extends" definition, and now gets the cryptic error message

Expected a value of type '(dynamic) => Widget', but got one of type '(int) => Text' 

To turn this in a compiler error at the right place, use

 implicit-dynamic: false 

One annoying downside of this is that you have to add the dynamic type explicitly, even when a method expects a dynamic type, e.g. if there is a method

Foo deserialize(Map<String, dynamic> jsonMap) 

you need to call it like this:

deserialize(<Map<String,dynamic>> {"key": "value"}); 

But I would still argue this feature is worth some additional boilerplate.

Is it possible to develop with flutter without an IDE?
I'm a bit old school in that I develop in generic text editors (vim and gedit on ubuntu, primarily). I'm interested in developing with flutter and built a container with the android sdk and flutter, but most tutorials seem to rely on using an IDE. Is there any tutorial out there that shows development on the command line, or similar? Thank you!

Little help here putting logic on icons
I have this list

final List<String> entries = <String>['Life', 'Car', 'Car']; 

then i try to generate 3 widgets each one with an icon depending on the values that have the array i tried in this way

 children:<Widget>[ Icon( entries=='Life'? Icons.favorite_border:Icons.directions_car, color: Colors.white, textDirection: TextDirection.ltr, size:50, ), 

but all widgets get the favorite_border icon instead of mixing between directions_car and favorite_border.

<b>Recap: Interact 2019 was... &#129512;&#127798;&#65039;&#128293;&#128165;&#128175;</b>
Hey everyone -- this is our last recap for the year. Enjoy and we'll see ya in 2020!Want to get it by email? <a href="https://flutterigniter.com/snacks/">Click here</a>.____<a href="https://developers.google.com/events/flutter-interact">Flutter Interact 2019</a> just wrapped up and there were some <a href="https://www.youtube.com/playlist?list=PLjxrf2q8roU0o0wKRJTjyN0pSUA6TI8lg">fantastic announcements and talks</a>.For those that have questioned whether or not Flutter is worth investing their time and mone, watch Interact and read the recaps. We believe Google’s continued commitment, as well as <a href="https://tech.ebayinc.com/product/under-the-hood-of-ebay-motors-new-app-powered-by-advanced-technology-like-flutter-ml-and-bff/">adoption by big players like eBay</a>, should help to convince you that Flutter isn’t going anywhere but up &#8599;&#65039;____One UI toolkit to rule them all... &#128081;In the <a href="https://youtu.be/NfNdXgJZfFo?list=PLjxrf2q8roU0o0wKRJTjyN0pSUA6TI8lg&t=875">Vision Keynote</a> (accompanying blog post <a href="https://developers.googleblog.com/2019/12/flutter-ui-ambient-computing.html">here</a>), Matias Duarte, winner of the “Best Dressed at Interact” award (that suit tho… &#128293;) discussed the concept of ambient computing and how it’s core to Flutter’s vision. The idea of using Flutter and only Flutter to build applications for mobile, web, watch, car, etc...is admittedly tantalizing.Here’s the TLDR; on ambient computing:<strong>Services and software need to be available wherever users need them</strong>...for those that are old enough to remember, we’ve heard a version of the “ambient computing” dream many years ago with Java and it’s friend Swing. While that dream was never truly realized because <a href="https://zef.me/java-swing-history-e1ea143460d6">things ultimately looked like sh*t</a>, we’re once again embarking on a similar journey with Flutter. We’re cautiously optimistic that the end result will be muchhhhh better &#128514;<strong>Multi-platform doesn’t mean sacrificing visual quality</strong>...let’s face it, we live in an era where there are more and more options when choosing what experiences we choose to use on a daily basis. Apps not only need to do what we want but they need to look good doing it…____Flutter 1.12 is here...&#128142;As most of us hoped for, <a href="https://youtu.be/ukLBCRBlIkk?list=PLjxrf2q8roU0o0wKRJTjyN0pSUA6TI8lg&t=422">Google announced Flutter 1.12</a> (<a href="https://flutter-widget.live/blog/release-notes-1.12.13">changelog</a>). While there are no earth-shattering announcements, there is <a href="https://medium.com/flutter/announcing-flutter-1-12-what-a-year-22c256ba525d">lots of progress</a>, which is what we love and have come to expect from the Flutter team. 4,571 issues closed and 1,905 PRs merged; not too shabby!<strong>Cupertino love</strong>...the Flutter team hasn’t forgotten about all of you Apple fanboys. Version 1.12 brings official iOS Dark Mode support as well as two new widgets: <a href="https://flutter-widget.live/widgets/CupertinoContextMenu">CupertinoContextMenu</a> and <a href="https://github.com/flutter/flutter/pull/42775">CupertinoSlidingSegmentedControl</a>.<strong>Flutter for web goes beta</strong>...in the spirit of all things ambient computing, the Flutter team announced that <a href="https://youtu.be/ukLBCRBlIkk?list=PLjxrf2q8roU0o0wKRJTjyN0pSUA6TI8lg&t=1257">Flutter for Web is now in beta</a> (accompanying <a href="https://medium.com/flutter/web-support-for-flutter-goes-beta-35b64a1217c0">blog post</a>)! Flutter apps created on the beta channel with web support enabled will now include a web/ directory that contains everything you need to run your project on the web. Support for plugins is also here with fan favorites like shared_preferences and many more already updated with web support.<strong>Flutter…

AnimatedContainer, expensive or no?
I want to check to be very clear on something. I've heard it said by people who should know that the AnimatedContainer will try to animate every property it can, not just the ones that have changed. This would mean it would be a very poor choice for people to overuse it for things that could be

How to clear AsyncMemoizer old memory ?
How to clear AsyncMemoizer? I need to refresh my tab controller screen after it's opened. But it's not getting updated because the Memoizer isn't allowing me to update the current state of the screen, I have used AsyncMemozier because my futurebuilder was going in a loop in a provider because of notifylisteners, And I was calling my method from a stateful Futurebulider.

How to capture errors and send platform-specific information to Sentry in Flutter?
One of the aspects of developing software is to handle errors and log them properly in order to mitigate them at the right time.When we develop for Flutter, indeed, we have several options to capture and log the errors. One of the greatest tools which come with an easy-to-use dart package is Sentry.io.It is not always easy to reproduce the errors that occur if there is no extra information about the platform or environment as recreating the exact same situation could be difficult and time-consuming.For more information, read my article here....

Packages a potential pitfall?
Note: purpose of this post is open discussion.I love flutter to say the least. But as I'm moving out from beginner to intermediate as flutter developer and apps I'm building are getting more and more complex. I myself find using packages sometimes to carry out native device functions or sometimes to be lazy and use cool looking ui widgets instead of building my own. But since most of these packages are built by enthusiastic developers, it is possibility that due to some reason the development of those packages stops abruptly. Which could in turn lead to minor to major changes in app. (I'm looking at you state management libraries).What are your view about it?
