I'm making an app which scan a QR code and get the version and error correcting level info of it.
How to deal with it.
I tried multiple plugins but i didn't found effective one that can get the version and the error corecting level of the code at the same time.
Please see these links to get you started.

There are many other links available. It's always better to try something first then post your problems here.
The version and error correcting level info are what i asked for..

I am a beginner in flutter and would like your help.
I want to get the Google Services Frameword Identifier (gsfid) in a flutter app, but i can't find any plugin for that. I found a fairly old post on how to do it using java, but I couldn't get it to work, as flutter, if I understood correctly, uses kotlin and unfortunately I'm neither a java nor kotlin expert.
I read all the stuff about deviceID and Android_id, which is confusing enough on its own without starting to mention other "unique" ids (e.g. ad id etc).
I have concluded that what suits me for use in the particular application I have designed is the gsf id.
So if anyone knows the subject and is kind enough to help me, I will be grateful and thank you in advance.

I tried to convert the java code I found se kotlin and connect it (methodChannel) to my flutter application, but without any luck
I am following a tutorial to use Custom Widgest in FlutterFlow, re-using dependencies from pub.dev. However many people in the YouTube comments (including myself) hit an error whilst trying to compile the custom widget. The widget is an official Flutter.Dev widget for a video player.
I have tried searching for this error, however most responses involve installing more packages and restarting Android Studio etc, however this error is happening within FlutterFlow itself, which I haven't seen an answer for.

Thankyou in advance!
First pf all you have to add dependenc of video player imleft side you are suggested to add video player dependency forst of all add it and you can esaily use it.
You can simply ignore the error because FlutterFlow can't detect the dependency in real-time.
Just hit Compile & Preview button and it magically works.
Recently, I watched the first introduction of Flutter originally named Sky on Youtube https://www.youtube.com/watch?time_continue=10&v=PnIWl33YMwA .
At 1:54 Eric Seidel says something like this - This all is loaded over the network. Dart code of the network. What happenend to it in Flutter?
Is it possible to load Dart code like new versions directly over the network without using the AppStore?
I'm not sure Eric was talking about the data or the actual code. It does sound like he meant both.
It may have been possible to load code over the network because on these early days they shipped the dart VM on releases and code was JIT compiled. Since late 2015 Flutter moved to Dart's AOT compilation (see this video).
So no, it's not possible to update your flutter apps through the network.
This all is loaded over the network. Dart code of the network
After watching the video, I got the context of the line. It means the data getting fetched from the network and the code written is in the Dart rather than Java.
I am trying to create an application that reads information from a Driving license and gives the result based on that. I am using Ionic framework for my app and have integrated the PDF417- phonegap plugin by MicroBlink with my app.
I followed all the instructions given at:
https://github.com/skifaster/pdf417-phonegap/blob/29cc6d8/README.md
The app is now successfully reading information from barcode and displaying it in an alert box on my screen. But I cannot find where the alert box is being generated from.
I need to know where the scan result is stored so that I can process the information further.
Can someone please help me with this?
as first, I would suggest using original MicroBlink repository instead of forked one. Using original repository guarantees having latest features and updates.
Next, here you have an example how scan is performed from javascript and how data is returned in JS callback. The example implementation raises alert with returned data.
Adobe AIR application which was working perfectly earlier; is not working now. No idea whether it is due to any recent change in Facebook or Adobe AIR.
I have added the component mx:HTML to display http://facebook.com content. In the development environment (Flash Builder 4.5) after logging in facebook successfully; I can see the TimeLine contents and updates properly. But after build when executed outside the IDE; I am able to login facebook but the timeline or updates are not being displayed properly.
Anybody facing similar issue and has a fix; please provide the solution.
uncaughtScriptException gives following two errors...
TypeError: Result of expression 'bigPipe' [undefined] is not an object.
ReferenceError: Can't find variable: console
I have similar issue, if you catch the javascript errors you will notice that facebook is using some library that fails in AIR, then if you google that exact error you will find similar issues. My solution was to use the FB API and reimplement the functionality(in my case share) , other alternatives is to fix that library or FB code to make it work. I don't remember the details but I fixed it a week ago.
Check the docs for catching the JS errors uncaughtScriptException
I am wondering if that library has code for each browser that it supports and on AIR it fails, maybe changing useragent will help, you need to check the javascript code to see where it fails
