inits | Init system for Node.js | Runtime Evironment library

Ok, here's how I ended up solving this problem. Probably not the "correct" solution, but it works for me.

The full code solution would be way too long and complicated and rely on too many local calls that would not make sense, so I'm trying to get this down to just some code snippets that will make sense to show how my solution works.

In each application, the Application.cfc looks a bit like this. Each app has a name set to the path of the Application.cfc. We do this because we often will run "training instances" of the codebase on the same server that point to an alternate DB schema so users can play around without corrupting production data.

You can use futurebuilder or you can use in initstate to fetch api

Please add the following to your manifest under the uses-permission tag:

As per @Lundin's suggestion, I have put a watchpoint on lpuart_dma_rx_tc_isr_clback function pointer variable. It exposed the out of index bug in my code. The bug is inside while loop in main.c.

There are several ways to solve this issue depending on the context. I try to avoid using BLoC instantiation with StatefulWidgets. And, I like to use Cubits in connection with Observers, depending on the event entering my stream. I have added most of them in the following code, which isn't all used but for you to look at as a reference. My code example eliminates the issues that you describe. I would be happy to help further if you could provide a minimum viable code.

The following code is an example that I have put together to demonstrate a possible strategy. The BLoC package website heavily inspires the code. It has the standard counter app that we are all familiar with and navigation functionality.

Please see the following code to see if it helps at all:

Please be sure to add flutter_bloc: ^8.0.1 to your pubspec.yaml file.

You are using Java 16 (as shown in the log file) with Maven. In this case, you should use TomEE in version 8.0.9 as this release contains important fixes regarding illegal reflective access (due to the use of Unsafe for proxy creation) in higher versions of Java. You find some details in https://issues.apache.org/jira/browse/TOMEE-3795

It looks like you are using a lower Java version for running your standalone TomEE deployment, which works as it isn't as restrictive as newer Java versions.

Side Note: Java 16 is end-of-life and you should better switch to Java 17.

SignalR for Flutter uses web sockets and SSE to receive messages from the SignalR service. If the app was terminated because the user restarted their phone or the OS shut down the app to save battery, these push notifications would not be received by the app.

To overcome this, app developers (and SignalR) have to use FCM on Android, and APNs on iOS (or FCM which will also use APNs on iOS). All other approaches will be more limited because the operating systems do not allow users to keep background processes running the entire time. This was actually allowed years ago, but the operating systems have made these changes to save the user battery - they enforce that all apps go through the same push notification medium - FCM on Android, APNs on iOS.

SignalR for Flutter uses neither FCM nor APNs. At it's current state, SignalR is not well suited for Android or iOS - take a look at the comments with people struggling with similar problems to you on How to use signalr in Android.

The simplest / easiest way to get started is to use Firebase Cloud Messaging.

• On Android, it will be used directly to send messages to devices, and
• on iOS, FCM will use APNs to reach devices reliably

Caveat: On Android, there is a more complicated alternative called unifiedpush, but the limitations include showing a notification to the user at all times to handle background notifications.

My analysis: This is all done based on my quick investigation by reading the pubspec.yaml, the GitHub issues on the original repo, the SignalR documentation, and some experience implementing Push Notifications for Flutter.

Disclosure: I just released a push notification library 2 days ago called push which would be well suited to these types of Push Notification packages making the transformation to using FCM on Android and APNs on iOS. However, as an app developer, in most cases, you should use firebase_messaging, not push.

You must add import 'dart:async'; to use unawaited and must set the minimum Dart SDK version to 2.15.0 or higher.

For older Dart versions, you can get unawaited from package:pedantic instead.

It can be a bug of that Flutter package, indeed. Have you tried to create an issue in GitHub of that package?

Secondly, during my development, I see several times when emulators just fail and real devices always work. The solution I used is - simply to do not test them on simulators. Real users never use simulators, aren't they?

It can be a bug of the library when running on x86 arch (the arch simulators use). Then, nobody with a real device (arm arch) will ever see the bug.

Thirdly, what about trying to use "cloud real devices" to test whether they work on real Pixel devices that you are worried about. There are many platforms that host some real devices and you can connect to them via a webpage and test your app.
