Would this be possible in Flutter?
Hey guys, I'm wondering if I could get your advice on how best to approach one key feature of an app I'm building with Flutter.I will do my best to explain but I can also create a demo in After Effects for clarity if I do a bad job of explaining!I want to create an interactive SVG. Imagine a grid. My dream for the UX is that the user starts the selection process on press down. The user can then drag around the SVG and when released, the element is selected. I'd also like to apply a "hover" effect on the element the user is over while the user is dragging.Would you be able to offer some advice with where would be best to start with this please? Would an example mocked up be more helpful?I did start building this in React Native and made good progress but I'm keen to use Flutter, thanks for any help!

Separate state to each ListTile
So I am using a SliverChildBuilderDelegate to build a ListTile of files. Each ListTile has a play icon to play the audio related to that file. I want the icon to change based on the state of the audio, whether it is playing or paused. How do you handle states in such situations? I can’t just use one state because if I change that then all the listTiles will change their icons too. I am using Provider as my state management

A way to “werror” in Flutter?
I currently use the lint package, but that only throw warnings when the rules are broken.What I currently want is something similar to the werror flag in c, where all the warnings are treated as an error, and you can’t run the code if there is any of the active rules are broken.Currently I have to manually set every rule active in the the package to error. But this has the problem of extending the file over 100 lines, and will not automatically update if dart of the lint package changes the active rules in an update.What do you recommend?

[provider] view model with collection of objects
Hello,I'm pretty new to flutter (and mobile development in general) and I'm trying to plan my app's architecture with provider.​I have a state model that has collection of objects that have a collection of objects inside as well (think collection of todo lists):

class StateModel extends ChangeNotifier { List<TodoList> todoLists; } 

simplified TodoList class looks like this:

class TodoList { int id; List<Item> items; } class Item { int id; String name; bool status; // true is done, false is not done } 

Now one of my Views is ListView of my todo lists (where I display only name) and that's east. But I want to have a todo list detail view (where data of single todo list is displayed) where I want to mark todo items as done (i.e. set their status to true). How should I do it? I could have method in StateModel which would find a TodoList object by id, then mark items as done. This could look something like this:

class StateModel extends ChangeNotifier { // (...) void markItemAsDone(listId, itemId) { // find todo list in StateModel // find item in given list // mark it as done // notifyListeners() } } 

But this seems wrong. What I would like to have is a way to get TodoList object view model and use its methods, not StateModel methods. How should I approach this? Can I have another view model (TodoListState), and have a collection of TodoListState objects in StateModel? Is this a use case for ProxyProvider?​I hope my question is clear, let me know if this needs more explanation.

Best way to share data across widgets (I need something like events)
Hello, I'm new to Flutter and Dart in general.I want to create a Bluetooth application, so I have the MainScreen widget (which will display all information of connected Bluetooth device) and the widget to choose which device to connect with (DiscoveryPage).Basically the structure is the following:

routes: <String, WidgetBuilder>{ '/': (context) => MainScreen(), '/settings': (context) => SettingsScreen(), '/discovery': (context) => DiscoveryPage(), }, 

So on the DiscoveryPage I'm using flutter_bluetooth_serial library, which strikes a function whenever a new device is found. What I want to do is share the device I am connected to from DiscoveryPage to MainScreen.Here is how I get new BT devices:

void _startDiscovery() { _streamSubscription = FlutterBluetoothSerial.instance.startDiscovery().listen((r) { setState(() { results.add(r); }); }); _streamSubscription.onDone(() { setState(() { isDiscovering = false; }); }); } 

Coming from a JS background I thought a global event could be the best solution, but as far as I know, this cannot be done in Flutter. How would you solve this problem?
