Love your tutorials, always well explained

[WolfenIM]

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

[ProgrammingwithPeter]

Nice, ninja style of try catch blocks !

[masoudbadremiran]

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

[Doesel]

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 :)

i am building the alarm app an facing issue in getting notification i am trying it on physical device but alarm does not ring when time matches can u help me with that

[johnnydriesen]

at 03:54 ...
Don't we have to use this.time = ... (in case of just time = ...) on lines 32 and 36 ?

[huzaifak_]

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

[ashishmishra]

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

[furkanakcakaya]

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

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'.
