A post to thank Flutter in whichever way it has helped me till date and share a simple state management plugin with the community
Hello World,It's been a over a year since I have fallen in love with Flutter and since then I have never looked back. Flutter and Dart have taught me a lot of things which has shaped my personality and has made me the way I am today. If someone (or some people) in the community think that making developers' lives easier and more productive is their responsibility, then I think it should even be my responsibility to help them in some or the other way. So I came up with a simple state management plugin, that makes things even easier. Zero complexity was the ultimate goal of the plugin, but the plugin is all about what could have been achieved. The basic approach of this plugin is to design a widget tree with respect to some variables and then update them as and when needed (with the help of this plugin).Updating would be as simple as attaching a notifier (n) to a widget (literally anywhere in the widget tree),
n - ()=>Text(variable)or (passing the required value to that part of the tree,n - (v)=>Text(v)Plugin: https://pub.dev/packages/notifier_plugin
GitHub: https://github.com/thehumankid/notifier_plugin
(The plugin does have other interesting features too)Thank you for everything Flutter 🤗 (The official team and all present and future contributors)

Hey guys, does any of you know any github repository where there is in_app_purchase product, which would remove ads from the phone for some amount of time?(Something like, buy premium with no ads for 2 months).Any link or sugestion would help. (Just please don't say "make two versions of the app, and why an user buys a product, you redirect him to download your second premium app)

Considering Flutter for Frontend
Just wanted to get the community's opinion on the current state of Flutter Web. We're looking at using Flutter for the front end to minimize the amount of platform specific code required and it'd be great if the web portion could also share the same code base. Can the majority of the mobile UI code be used for deploying to Flutter Web, or is there still a lot of things that will need to be done twice? Thank!

<b>State Management could have never been easier!</b>
One simple approach.
Design a widget tree with respect to certain variables and then just update parts of your widget tree as per your requirements. That's all you need to design a dynamic UI in Flutter.
How can one update/rebuild a part of them at ease? That's exactly what the below plugin is for.<a href="https://pub.dev/packages/notifier_plugin">https://pub.dev/packages/notifier_plugin</a>Notifier n = Notifier();
int i = 0;// [...Widget Tree...]
FlatButton(
child: n - ()=>Text(i.toString()) // Attaching the Notifier to a part of the widget tree
onTap: (){
++i;
n(); // All the widgets attached to this Notifier get re-built
}
)
// [...]While this might seem like a something a bit simpler than what currently exists, it's real power can only be felt while actually developing UI keeping the above approach in mind.One could even pass a value to another corner of the app with the help of a `ValNotifier`,ValNotifier v = ValNotifier(initalVal: 0);
// [...Some Widget Tree...]
FlatButton(
child: v - (value)=>Text(value.toString()),
onTap: ()=>v(v.val+1)
)
// [...]
// Note: Both Notifier and ValNotifier can work with multiple widgetsJust want to update a widget tree without explicitly defining it? The plugin has got you covered.int i = 0;// [...Widget Tree...]
~(n) => FlatButton(
child: Text(i.toString()) // Attaching the Notifier to a part of the widget tree
onTap: (){
++i;
n(); // All the widgets attached to this Notifier get re-built
}
)
// [...]A ValNotifier can be obtained in a similar manner by adding an extra parameter,
~(n,v)=>SomeWidgetTree()If this still sounds unrelatable, then just imagine practically implementing some UI logic without really thinking about any other concept....just the above approach. (Design with respect to certain variables and then update as and when needed and see the ease it will provide...the ease would be felt to such an extent that only the app's logic would be there in the developer's mind while using the approach)While the basic features of the plugin will cover most of needs, here's a list of just few of the features the plugin otherwise offers,Perform (foward/reverse/circular) animations with the help of a ValNotifier/TweenNotifier (just specify the start and end value and the duration [and curve] and the plugin shall handle the rest for you)Performing http requests with common parameters have got easier than ever! Every time you request from a HttpNotifier, you'll just have to overwrite the parameters that were previously cached or send a request directly with them, thereby reducing the overall boiler-plate code.Almost any common listenable object (ChangeNotifier, ValueNotifier, Stream(Controller), Notifier, ValNotifier, ...(including controllers)) can be easily be connected to a widget for updates. So whenever the listenable object gets notified or receives a new value, the connected widget will automatically rebuild that part of the widget tree without any hassles.A few examples:changeNotifier - () => Text("Will surely accept no parameters"),
valueNotifier - (value) => Text("Will surely accept a single parameter ($value)"),
stream - (snapshot) => Text(snapshot.hasError?"Error: ${snapshot.error}":"Data: ${<a href="https://snapshot.data">snapshot.data</a>}")And since a controller is very likely to be a ChangeNotifier or ValueNotifier,textEditingController - (textEditingValue) => Text(textEditingValue.text), // ValueNotifier
scrollController - () => Text(scrollController.offset.toString()), // ChangeNotifierEver felt that dealing with Future(s) or async objects is not that intuitive or has too much code to deal with? The plugin has solved that problem too.future - (snapshot)=>DealWithIt(snapshot)
WFuture(future) - (data)=>Text(data.toString()) // Loading and error widget were predefinedTo know more about the other features offered by the plugin, head over to the links given below.Plugin: <a href="https:/…

Help improve the dart language
I'm an avid fan of dart but like any languages it has its problems (no this isn't a post about enums :) .One ongoing problem I have with the language is discovering what exceptions a particular method is going to throw.The date language guide recommends adding details of what exceptions are thrown but the reality is that they rarely are.I think there are two root causes of this.1) it requires writing documentation and most developers hate writing documentation. 2) it's often hard to determine what exceptions your method throws because the methods that you call don't document their exceptions.This problem then bubbles up the code path and you have the situation as we have today where exceptions are essentially not documented.I believe there is an easy, non invasive, way of solving this problem.The idea is to add a lint that tells developers that they are missing documentation for an exception.With a lint in place the IDEs can be modified to add a quick fix which automatically adds the exception to the documentation.With little effort we can get a dramatic improvement in exception documentation which will benefit everyone in the community.As it's implemented as a lint it can be globally or locally disabled if you find the lint offensive.I've raised an issue on the dartlang repo.https://github.com/dart-lang/linter/issues/2246If you think this issue would benefit the community could you please vote or comment on the issue.
