My code runs in debug console instead of terminal and it doesn't takes user inputs even though there is no error.

[@MohamedAbauze]

thanks man your solve my problem thankssss

[@user-nf9sz6cy7l]

How to find the data type entered in terminal? Because the only data type I'm getting is " String " even tho I put numbers in there

[@siddiquisharique]

You have to convert string values to double or integers.

[@ericberg2131]

You have to run this program from the terminal for it to work properly

[@chadkhan277]

@@JohanJurrius sir i face same problem. what can i do now?

[@Kyun_____]

Thanks

[@texsesyt2902]

for any one having error just put ! at the end.
int num = int.parse( stdin.readLineSync() ! );

[@younesferhat6092]

thanks man

[@JoneeL]

or it needs to be a string so you can do int num = int.parse( "${ stdin.readLineSync }" ); this will also act like a string syntax is bit harder to read.

[@omerfarukseckin]

my code isn't working ı can't understand where is my mistake

[@nirojthapa5077]

how to fix this while taking input
Error: The argument type 'String?' can't be assigned to the parameter type 'String' because 'String?' is nullable and 'String' isn't.

[@JohanJurrius]

Did you check out this video of mine? th-cam.com/video/LulvhhDiqQw/w-d-xo.html . In the description of the videos you will find a link to the playlist. Better to follow the playlist.

[@luisgassier7251]

String? tipo = stdin.readLineSync();
opc = int.parse(tipo!);

[@abdulfatahbajeh6542]

Same issue over here

[@siddiquisharique]

Use var instead of String

[@ahmedbahram4653]

thank u

[@mohsenahmedofficial7215]

thx

[@josephakintola5988]

Mine is saying global something

[@ianrafaeltoh7679]

not working, it will freeze the console

[@zakariahouache5442]

void main() {
print('what is your age');
String age=stdin.readLineSync();
print("your age is = $age!");
}
It says there is an error here where is the error in stdi

[@JohanJurrius]

What is the error?

[@NitinVarma]

It's a null safety error.
Try using
Syntax: String?
or
Syntax: stdin.readLineSync()!;

[@majdkillawe3193]

*** SOLUTION FOR THE INT.PARSE **
int x =int.parse(stdin.readLineSync()!)
