Firebase storage tutorial
I'm currently playing with firebase storage, by using the firebase_storage package. But there are no good tutorials, and the documentation is only for Swift and Kotlin. Does someone know a good tutorial to start with firebase storage?

ISO an example for querying Firestore DB based on geopoints?
I currently have a Map screen and a Firestore query to "grab everything" from the DB. But I ultimately want a query that "grabs everything within a 5 mile radius of my objects".Each object in my database has a variable named geopoint that is an Array<double> that is where the location is stored.Any help, example, or direction would be wonderful!

Discussion : native Chrome support
Hello,Recently, Flutter Web has been announced and allows any Flutter app that doesn't rely on Method Channel to work on the web. I have tested it myself, and the performance is clearly not there, compared to a AOT compiled application for iOS / Android. Since Dart, is compiled to Javascript which is itself interpreted, this not very surprising.Since Google owns Chrome and Flutter, I was wondering if it could add Flutter / Dart support directly to Chrome. The app could either be served as Dart code and just-in-time compiled by the browser or directly as byte / machine code. I know this is clearly not compliant with web standards, but the goal of this post is to discuss what you would think about it.

[charts_flutter] Has anyone managed to get `selectionChanged` callback to work properly for gauge chart?
So i've been struggling with this bug for a few months now, have made several SO posts and opened issues on the charts Github repo to no response so this is my final straw attempt to try and find someone who may have a better idea of what I'm potentially doing wrong or whether this is a bug with the charts package.Using the gauge.dart file from the example here, i've just added a changedListener callback to get which segment the user has clicked.It works as expected only for 3 of the 4 segments, but clicking the last segment triggers an exception if it's tapped towards the end of it's region (depending on what random value it has been given from the example, if it's a relatively small segment then the whole segment give the same error).

static List<charts.Series<GaugeSegment, String>> _createRandomData() { final random = new Random(); final data = [ new GaugeSegment('Low', random.nextInt(100)), new GaugeSegment('Acceptable', random.nextInt(100)), new GaugeSegment('High', random.nextInt(100)), new GaugeSegment('Highly Unusual', random.nextInt(100)), ]; return [ new charts.Series<GaugeSegment, String>( id: 'Segments', domainFn: (GaugeSegment segment, _) => segment.segment, measureFn: (GaugeSegment segment, _) => segment.size, data: data, ) ]; } @override Widget build(BuildContext context) { return new charts.PieChart(seriesList, animate: animate, // added selectionModels to pass in _onSelectionChanged callback selectionModels: [ new charts.SelectionModelConfig( type: charts.SelectionModelType.info, changedListener: _onSelectionChanged, ) ], defaultRenderer: new charts.ArcRendererConfig( arcWidth: 30, startAngle: 4 / 5 * pi, arcLength: 7 / 5 * pi)); } _onSelectionChanged(charts.SelectionModel model) { final selectedDatum = model.selectedDatum; print("DATUM: ${selectedDatum.first.datum}"); if (selectedDatum.isNotEmpty) { print('IS_NOT_EMPTY'); } } 

Will give this exception

The following StateError was thrown while handling a gesture: Bad state: No element When the exception was thrown, this was the stack #0 List.first (dart:core-patch/array.dart:202:5) #1 GaugeChart._onSelectionChanged package:example/pie_chart/gauge.dart:89 #2 MutableSelectionModel.updateSelection.<anonymous closure> package:charts_common/…/selection_model/selection_model.dart:178 #3 List.forEach (dart:core-patch/growable_array.dart:283:8) #4 MutableSelectionModel.updateSelection package:charts_common/…/selection_model/selection_model.dart:178 ...
