Finally understood isolates!!! Have been trying for weeks to understand watching tutorials, blogs.... Seemed so complex....Thanks for breaking it down simply.. I would expect if make a tutorial applying with a practical example
I just come to discover the channel but the way you break the complexity of the concept of Isolate doesn't give me an option other than my subscription to you. Really like it. Please keep going. I hope it the beginning of a long coding skills journey with you❤
help please i keep getting error: Bad state: The BackgroundIsolateBinaryMessenger.instance value is invalid until BackgroundIsolateBinaryMessenger.ensureInitialized is executed.
can i use isolate in background like when get notification in fcm backgroundhandler for playing custom-sound or not, what i seeing is , it is taking time to play ringtone any suggestion on this
how about to pass big json data to the second isolate, and get it from that isolate, as far as I know, deserialization of the message from the second isolate requires memory resources
Sir I want to fetch data from an api even if my app is terminated and send the notification. Sending notification is done but how to run any function in background if my app is terminated plz help me ❤❤
In general it’s not allowed, if every app starts to call API when it’s terminated then phone battery will simply die. But it’s possible, you have to register background service on Android and iOS which will give access to run in background. There is limitation on that too.
@@CodeXdev Thanks for the quick explanation. After a bit of research, I found out that the Image.asset function rendering the gif image is also an async function. That means the calculation function takes higher priority than the Image.asset and Image.asset is executed until the calculation function is completed.
Hi, I am facing a problem when i nevigate back using navigator.pop with sending data back with it such as an object and when i try to setState() the ui dosnt update the date/show unless i hot reload. So many people are facing this problem you can also see it on stackoverflow but there is no explaination.
Nice video! But I still cant implement it correctly in my code. I have a quite expensive function that should return Uint8list to then display it on screen, but flutter is throwing an error saying that 'object is unsendable' :(
It's weird how many devs don't get threading/concurrency. It's been weird for about 20 years, actually. The C++ devs had to figure out mutexes as soon as the Pentium Pro was a thing LOL. But now I mean come on everybody knows Python but how many people understand conceptually how to use starmap/join/sharedctypes? It's super easy to implement, but you need to understand what you're actually doing communicating with processes and using pipes and shared memory. Apparently even in 2024 the Flutter team thinks any access to shared memory is just too complicated for the type of devs looking for a cross-platform framework. Makes me think I should just be writing native code.
Btw just wandering why you are not using camera in tutorial now. It would be really great if you start to use camera again and it will be more interactive with camera.
I hardly manage to create tutorial videos at home, (My toddler needs my time) So, with cartoon it’s quick and I don’t have to do setup for recording environment 😅
