Hello @smartherd. thanks for the great tutorial series. I love this video but I feel that strings would explain this concept better for the example rather than integers because integers multiplied in any order will give the same result but strings concatenated in different orders will show the difference more clearly. I might be wrong though and if I am I stand corrected.

I tried to use { int height = 10 } when defining the function, but Dart Editor produced an error mentioning I can't use "=" sign while setting default parameter value, and advised me to replace = sign with a colon ":". I used colon instead of "=" sign and it worked. But same time this equal sign is working in your example... Is there any version difference, and this usage of equal sign is obsolete in latest versions?. I am using Dark SDK 1.10.1? Please advice.

@cybernerd7492 3 года назад

update dart sdk the latest version is 2.13.0

@hit1599 3 года назад

Can default values be used for optional parameters too?

@cybernerd7492 3 года назад

yes

@m.praveenkumar3702 Год назад

Great explanation. What is the difference between [ ] & { } in function parameters

@somtoonwuagba7448 Год назад

The square bracket [ ] is used in positional optional parameter. The curly bracket { } is used in named and default optional parameter.

@shivamrathore8009 3 года назад

if the findvolume functions return an integer then, why you haven't specified the return type and also why the code don't provide error

Thanks for the tutorial. They are neat and simple. I have a question in flutter we use a constructor like this : constructor({this.some_value}); some_value is a variable define in that class. Can u please explain the above constructor. Im confused where is the body of the constructor method??
