Best resources for technical paper about Flutter
I am currently writing my diploma thesis (kind of like a technical paper) for school about Flutter. I am still not sure which aspect I will focus on but probably something like what makes it so unique and what opportunities it creates.I am currently on the search for interesting resources about Flutter on a more technical level. Most resources out there are tutorials of some sort which are interesting but not really what helps me.Does anyone know interesting books, articles, blog posts about that or knows where I should be looking for them?Thanks in advance :)

Monitoring / security
Hello how are you? I'm new to the area, and I would like to ask a question. Do you want to create an application in flutter, monitoring / security, and would like to know if you can receive video and audio and real-time location of the application for a web system, like an administration panel.

How to enable a child component to make changes to a parent's appbar?
Imagine the following scenario - the app has a global Scaffold with a global AppBar. The body of the Scaffold is one of many app components. Each component would have the global appbar render differently and also have access to the appbar's TabController (so that listeners can be attached to

Compute function make a loop
Hi , guys, I would like someone could tell me , why when I use compute function, it makes the result as loop?. Here mi codeclass SearchMetodos {Future<List<ContactModel>> buildFiltroLista(var filtered) async {
List<ContactModel> contactList = [];
_contacts = filtered;
try {
if (filtered != null) {
for (int i = 0; filtered.length - 1 >= i; i++) {
contactList.add(ContactModel(
id: i.toString(),
names: _contacts.elementAt(i).displayName,
lastNames: _contacts.elementAt(i).familyName,
emails: _contacts.elementAt(i).emails,
phones: _contacts.elementAt(i).phones,
avatar: _contacts.elementAt(i).avatar,
));
}
}
} catch (e) {
print('Error buildListaFiltro' + e.toString());
}
return contactList;
},}Then another class call this method with compute , here :class SearchContactPage extends StatefulWidget {var _search = SearchMetodos();Future<List<ContactModel>> _suggestions() async {
var contactos = await ContactsService.getContacts();
List<ContactModel> miList = [];
miList = await compute (_search.buildFiltroLista, contactos);
setState(() {
suggetionsList = miList;
});
return suggetionsList;
},}Thanks:)

StatefulWidget Vs Provider for Bottom navigation bar?
I have a StatefulWidget with a bottom navigation bar with 4 tabs. I am recently getting familiarized to Provider and found this article to use provider + StatelessWidget for navigating the tabs instead of using the current StatefulWidget.The StatefulWidget is a simple setState and is used only for 1 page so wont be needing state of the bottom nav bar anywhere elseI'm trying to understand how using Provider + StatelessWidget fares against plain StatefulWidget from a performance standpoint?

Is there a way to detect the time zone of a device that also takes DST into account?
As mentioned in the title. Is there a way to detect the time zone of the device? I know of the timezone plugin and tried it, but it seems that you have to set the time zone manually and I don't want my users to pick it them self.I have an app and a website both made using Flutter. To work properly they need to know the time zone of a device. Most of the year this wasn't a problem but recently a user of mine in the US mentioned that the time in the app was off, since they changed to dst before europe does.

I was able to Port my React Native app to Flutter in 3 days
Everything is so much better. The big advantage is there's a single source of truth for how to do things the right way. You don't need to use 36 different third-party modules to build an extremely basic project.Material design, of course built in, state management, built in. Navigation...This unto itself makes stuff much easier to get and keep working.Next the Dart programing language. I'm upset this wasn't adopted as a browser language. Dart is what Typescript should of been. The JS ecosystem is a convoluted nightmare. I don't know if I'll need to build a server from scratch anytime soon, but I think i might use Dart for some AWS lambdasBuild tools.Compared to RN's Expo, flutter takes a bit longer . Installing Android studio isn't fun. Yet once you do it's a much better experience. Apps debug very well.Overall Google has much tighter control over the flutter ecosystem than FB does over React's.In a way I think Flutter is built off the lessions learned from React Native paving the way. It's shocking how easy things are .Here's my original post from last week before I took the dive.https://www.reddit.com/r/FlutterDev/comments/fhth7p/downsides_of_switching_from_react_native_to/
