How to highlight a displayed text in flutter?
I’m building a mock writing test app with flutter. I need to display the writing prompt in the top of the screen while the user can write the essay below.I’d like to allow the user to select the key words in the prompt and highlight them to help them stay focused on the topic while writing. How can it be achieved?

Asynchronous Programming in Flutter with Dart (IUE Presentation)
I recently gave a presentation in our university about Flutter and Dart. Please enjoy: https://www.youtube.com/watch?v=yyvTrXCDdYgFrom the video description:Understanding how asynchronous programming works can be a challenge. In this talk tried to give an intuitive introduction to it and compared it to alternatives. I try to answer these questions throughout the presentation:- What can you with Dart?- Why should you use Dart and Flutter?- What is asynchronous programming and how does it relate to callback functions, threads or promises/futures?- How can we write asynchronous code in Dart?- How does asynchrony help in Flutter?This was a presentation that I gave in Izmir University of Economics. It is an improved version of a talk I gave about a month earlier: https://gdgizmir.org/schedule/day1?se...I use ideas from Florian Loitsch's talk in 2015 https://www.youtube.com/watch?v=MUDOI... Hope you find it useful!​

Help a friend out
I made a custom input widget by wrapping Textfield in some widgets and so on. Now I can't reach the onChanged property directly from input. I tried making a property in my custom widget but couldn't implement it properly. I googled passing variables between widgets and it seems a hard thing to do. So any help?

I’m a CTO for an IOT startup, I love flutter. Can my team use it for desktop, web, and mobile? If so what are the limitations?
Here are some of the features the app should support cross-platform:Real-time analyticsQR code scanningAdmin like dashboardGeo location / mapping libsNetwork topology ux ( with drag and drop )I’m a Go, python, NodeJS developer and looking at Dart, I’m not too overwhelmed by the learning curve.Im not sure if flutter can do desktop and web and share the same assets and modules.Any advice is appreciated as this decision is highly critical.

Connecting to Dart VM Service..
I'm trying to test a simple JSON RPC Java client, and connect to the Dart VM Service using TCPover a Socket, sending an initial JSON "packet" and looking for a response from the server.It's being run from the desktop on Windows. Is there any command I should be entering from a command line to get the server going, and what hostname and port number should be used for the Socket. Also, what should the initial JSON "packet" be? 'getVersion'? I've been looking at the vm/service notes. Thanks!

Detect widget visibility?

Is there an alternative to Firebase?
Is there any other solution giving me the same features: scaling, authentication, security, cloud hosted, nosql-db, flutter integration?​I look for an easy solution that can be ported if needed. Firebase seems to lock me in to google.For Back4App(Parse) I don't seem to find code examples for flutter on their page.Kuzzle seems to be quite expensive.Other options either aren't cloud hosted and/or also vendor locked-in.
