State Management/Database components...
I am 2 months into Flutter/Dart learning. So far I am amazed at what can be done, but maybe I'm totally missing something. This is not a complaint, but perhaps a bit of confusion. I come from 35 years building DOS, then Windows client server business apps, the last 20 in Delphi/Pascal.Basically, state was not an issue and database usage was as easy as buy/write/share a database library/package where the boilerplate can live and from the developer's point of view:Establish your database connection (login to SQL, noSQL, flat file...)Create table (container) level components, datasets that hold the query (sql...)Connect your visual components (grids/lists/dropdowns) to the datasets. User actions take you from there.I know, and can see the beauty of streams of data that update your chat, or messaging app, but honestly, in my 35 years I have only needed that in a few apps. Mostly business apps are: collect data, present data, manipulate data, post data, report on the data.I see Flutter as an excellent way to get data in, and probably do everything else, but I don't understand why there is so much boilerplate code required to do what seems to be so simple. There are soooo many great widgets and packages and whole apps you can download for free, but is there a simple database CRUD package without all the boilerplate?​Thanks for leaving me space to vent lol

I wanted to create a game with a LAN multiplayer. However I couldn't find any easy methods to transfer data between devices on LAN. Hence I eventually created my own.client_server_lanPlease can I have opinions (and maybe even contributions) on this package. I've also published it on pub.dev so feel free to import it using that.

Hope this package will be of use to everyone! It's a simple Flutter wrapper around the DartPad web embedding, letting you include code snippets and DartPad in your Flutter Web applications.!Currently there is no plans on making it available for Android/iOS/Desktop.

Getter methods in Widgets Usage
```dart class Example extends StatelessWidget {Example({ Key key, this.value, this.height }) : super(key: key);final String value; final double height;String get _output => value.toString(); double get _margin => (height / 10); } ```I saw this example and I was confused. And this is not the first time I saw this. a couple of different projects or repo has this getter method implemented.If I am not wrong, I thought having a getter method is to be used with an instance of an Object, not inside of the object.For example (from Dart language tour):```dart class Rectangle { num left, top, width, height;Rectangle(this.left, this.top, this.width, this.height);// Define two calculated properties: right and bottom. num get right => left + width; set right(num value) => left = value - width; num get bottom => top + height; set bottom(num value) => top = value - height; }void main() { var rect = Rectangle(3, 4, 20, 15); assert(rect.left == 3); rect.right = 12; assert(rect.left == -8); } ```From dart style guide: DO use getters for operations that conceptually access properties.If I were to change the first example, it would look like this:```dart class Example extends StatelessWidget {Example({ Key key, this.value, this.height }) : super(key: key);final String value; final double height;@override Widget build(BuildContext context) {final String _output = value.toString(); final double _margin = (height / 10);... } ```I changed the getter method to a variable and it still works.Am I missing something?

Something that I think would make Flutter imeasurably better than it currently is right now
Automatic indentation detection similar to python, in order to remove the amount of brackets and commas needed in order to crate widgets.I'm not a big fan of python (I come from a C++ background) but to say it handles readability well is an understatement. Right now, I think Flutters biggest issue (outside of technical issues that may arise) is the readability of it.I'll give an example piece of code:

class FirstScreen extends StatelessWidget { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('First Screen'), ), body: Center( child: RaisedButton( child: const Text('Go to Second'), onPressed: () { Navigator .of(context) .push(MaterialPageRoute(builder: (_) => SecondScreen())); }, ), ), ); } } 

Which to me, looks very busy for something so simple. Now imagine this:

class FirstScreen extends StatelessWidget @override Widget build(BuildContext context) Scaffold scaffold appBar: AppBar title: const Text('First Screen') body: Center child: RaisedButton child: const Text('Go to Second') onPressed(): Navigator .of(context) .push(MaterialPageRoute(builder: (_) => SecondScreen()) return scaffold 

With a few adjustements to the interperator (probably a rather heft task) you could improve readability, and reduce complexity and space very quickly!Any thoughts from the community? Is flutter open source enough that this could be something worked on for testing?
