Show me your main.dart - Flutter research

Keff on August 31, 2021

Do you work on a Flutter project? If so, please share your main.dart file with me (if you want and can). I'm researching how people organize their...

Which editor is this?
*note newbie here

Keff • Sep 1 '21

I think it's not an editor, most likely something like carbon, it converts code into imagesx like the one shown above! A rather neat site

MANUMRIGANK • Sep 1 '21

Oh!
Thanks

Hey, Sorry for the late reply. @nombrekeff is right. Its a code beautifier ray.so . But the one Keff mentioned also does the same job :)

Thanks
Can I somehow get this color and/or Background in VS Code?

Here's mine and I have to admit, i'm excited about Riverpod. In my "InitAppCore"-Widget i'm registering all the Providers I globally need. This is bloating my widgettree. I heavily depend on the concept of ProxyProviders do you know if thats possible with RiverPod?:

import 'package:flutter/material.dart';
import 'package:AppName/src/presentation/widgets/widgets.dart';
import 'main.reflectable.dart';
import 'src/app.dart';

void main() {
  initializeReflectable();
  WidgetsFlutterBinding.ensureInitialized();
  runApp(SystemConfig(child: InitAppCore(child: AppName())));
}

Thanks for the addition, I have not used proxy providers not riverpod, but I found this issue where they talk about it: github.com/rrousselGit/river_pod/i...

Just as a little tip, you can add codeblocks to highlight your code. Like this:

Hi Keff, thank you for finding this discussion. I think this is holding me back then from using Riverpod then. I use the proxyprovider for providing a callbackfunction from the authenticator to my grpc client, so the grpcclient knows nothing about the authenticator but can always ask for an id token.
I can think of a simple solution for my bloated widgettree, if i build one inherited widget that registers all the objects in a map[class]object and just provides a getter function.

GrpcClient _initGrpcClient(
    BuildContext ctx, Future<String> Function([bool]) idToken) {
  return GrpcClient(
      GrpcSetupParameter(
          remoteHost: SystemConfig.of(ctx).getValue<String>('backendUrl'),
          remotePort: SystemConfig.of(ctx).getValue<int>('backendPort'),
          options: ChannelOptions(
            credentials: ChannelCredentials.secure(),
            idleTimeout: Duration(minutes: 1),
          )),
      interceptorBuilder: () => [
            MyAuthInterceptor.build(metadataProvider: [
              MyAuthorizationMetadataProvider(idToken: idToken),
            ])
          ],
      serviceBuilder: (c, i) => [
            FileTransferService(c, [
              i<MyAuthInterceptor>(),
            ]),
            UserProfileService(c, [
              i<MyAuthInterceptor>(),
            ]),
            SomeServiceClass(c, [
              i<MyAuthInterceptor>(),
            ]),
            SomeServiceClass(c, [i<MyAuthInterceptor>()]),
          ]);
}

Yeah I don't now much about Riverpod, but maybe @iizmotabar knows as he has been using it.

Aviad • Sep 1 '21 • Edited

Hi, this is mine:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await GetStorage.init('MainStorage');
  await PushNotificationService.initializeApp();
  initializeDateFormatting().then(
    (_) => runApp(
      MyApp(),
    ),
  );
}

Keff • Aug 31 '21

I'll start, this is one of mine:

import 'package:flutter/material.dart';
import 'package:pegues/api/local/loading.dart';
import 'package:pegues/app.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  Loading.setup();

  runApp(const PeguesApp());
}

Would you mind sharing it? no problem if you dont't, but I'd love to see it. Also, have you always done your main.dart file like that, or have experimented and landed on that specific way?

Here's mine:
using catcher plugins

Keff • Aug 31 '21

Thanks for the addition @cahyowhy . I like that you're handling errors, great stuff! did not know about catcher either (I'm discovering a load of cool packages from this post), we use Sentry at our company for this.
