children: [
Icon(
Icons.signal_cellular_connected_no_internet_4_bar_outlined,

else if (snapshot.hasData)
return snapshot.data["chapters"]
.map<Widget>(
(imgSrc) => InteractiveViewer(
child: Image.network(

Salaries
Hey there,I am 17 years of age and currently enrolled in a school program where I work 4 days a week (as a flutter dev) and go to school for 1 day a week. Currently I earn little, because of restrictions on the school program. But next year I will probably get a real contract because the school program will be over, around how much would I earn then? I am living in Belgium, Europe.

Cloud storage provider for music streaming
As an intro, I'm developing an app with Flutter that has an audio section.I would like to address two subjects.For the moment the audio is stored in the cloud, more specific using Firebase. The main problem is that the pricing is not very supportive when the bandwidth threshold is exceeded. Also, as I discovered, each song is downloaded completely when trying to play it. Therefore, it doesn't matter that I want play 10 seconds or 1 minute of a song, the same traffic is generated. I'm using just_audio package as audio library and I'm wondering if there is a solution to integrate a stream base solution that implies buffering.As I've seen in the debug logs, a HTTP request is sent every time a song (from the cloud) is requested to play. Now, my concerns are that I can't use just_audio for streaming. Is there a cloud solution that fulfills a good compromise between price and bandwidth, even if the song is downloaded entirely each time the play action is required? I'm taking in consideration to develop an offline mode for the audio section, so that each song could be played from the local memory. Even so, it must be a user option, not a by default feature.

If so, are there any obvious advantages?I saw comment on slack group that people experience much higher cpu usage and bigger memory footprint. Has anyone tried?

A dropdown box placement and keyboard issue which is annoying but has got ignored since some time.
If in a screen you have a textfield and a dropdown and you click on the text field, the keyboard appears. After that if you click on the dropdown the keyboard disappears and the widgets crawl to bottom of screen. But the dropdown options keep hanging at the initial position instead of crawling back to bottom with the dropdown.Here is an open issue to upvote - https://github.com/flutter/flutter/issues/46676

What do you use for error handling or logging?
I was curious if you guys use any tools or software for error handling and remote loggingI needed a way to catch errors on the app and log them on my server for debugging later, but instead of building that myself I wanted to know if there's already existing solutions I can use

Aqueduct is not dead!
You may have heard that stable kernel is no longer going to support Aqueduct.Rest assured that Aqueduct is not dead.A coalition of developers are now getting organised to provide ongoing development and support for the new Aqueduct.If you want to get involved with aqueduct (soon to be renamed) then you can join the discord discussion at:https://discord.gg/NJAktS5bWe are setting up a meeting to discuss the foundations of the community around the new aqueduct:https://www.when2meet.com/?11431831-4XR9DHop into the above meeting link to indicate your time preferences.The meeting will be held on the discord server noted above.For those of you who don't know what aqueduct is:Aqueduct essentially allows you to write your back end in dart.It acts as a REST endpoint for your Flutter apps and includes support for postgres (DB) and a raft of other technologies.The core reason to use Aqueduct is so that you can use a single language for both your frontend (flutter) and backend development and get the significant productivity improvements from doing so.More announcements on the direction and support mechanisms for the new aqueduct will be made over the coming weeks.

Building your own Audio Broadcasting application like clubhouse
Clubhouse is one of the biggest social media platform of 2021. Drop in chats where multiple broadcasters can share their thoughts to audiences was a new concept and we are seeing many apps with a similar use case.
I tried building an app similar to clubhouse using the Agora Flutter SDK. The app can be used for live audio streaming where a broadcaster can create a channel and other broadcasters and audiences can join the channel.You can go ahead and read more about it in my blog over here: https://www.agora.io/en/blog/building-your-own-audio-streaming-application-using-the-agora-flutter-sdk/You can also have a look at the code for the same over here: https://github.com/Meherdeep/agora-flutter-audio-broadcastingPlease let me know what you think about it, I would love to hear how I can improve on this.
