Flutter Tutorial for Beginners #29 - Error Handling

Nice, ninja style of try catch blocks !

I see your GraphQL videos that was great but a bit outdated in apollo-client section could you please create another series on GraphQL thanks

Thank you, master! Can't wait for the next videos

Love your tutorials, always well explained

I am so amazed with your videos courses.
Can you please give course using flutter with mysql?

Is this the correct way to catch the API error.
Or Probably you should have printed the error object getting from the API.

Great tutorials, thank you for this :)

Question: Why didn’t you just try/catch the request, because this is the most important part? And you would exactly know what is not working. The map error is not that obvious, at least to a beginner :)

Super video brother, Thanks for this video.

Thank You !

Error: Entrypoint doesn't contain a main function

If you are getting a substring of instance.time in loading.dart, make sure errors are also handled there. I learned this the hard way after spending 2 hours debugging world_time.dart.

Should I , as a flutter developer, use try&catch blocks everywhere that an error can happen?

you are awesome

you are awesome

I got an error in my flutter program using the whenever I use my slider
It says invalid double

It doesn't show the catch message pls help me

i just wonder what happen if status return not success (status != 200). So how we handle it and show the message error?

try and catch throws an error on the IDE. How do I resolve?

Hi I cannot see the console in the Run window can anyone please help? I am Using Android studio 4.1.0

Red screen of death lmao haha

Thanks alot. It's the best tutorial for flutter beginners.

What is invalid depfile😭😭

setState() method not update the data after response any guidance for this sir please

These errors are coming PLEASE HELP MEEE---
Non-nullable instance field 'time' must be initialized.
The parameter 'location' can't have a value of 'null' because of its type, but the implicit default value is 'null'.
The parameter 'flag' can't have a value of 'null' because of its type, but the implicit default value is 'null'.
The parameter 'url' can't have a value of 'null' because of its type, but the implicit default value is 'null'.

Now flutter is updated, so we do not need this extra
Print('could not get time data');

Well explained :) Thanks
However, am stuck with this error => I/flutter ( 5673): caught error: SocketException: Failed host lookup: 'worldtimeapi.org' (OS Error: No address associated with hostname, errno = 7)

Flutter automatically throws an exception now!
