Proper Syntax When Using dot Operator in String Interpolation in Dart

In Dart/Flutter, suppose you have an instance a of Class Y.

Class Y has a property, property1.

You want to print that property using string interpolation like so:

print('the thing I want to see in the console is: $a.property1');

But you can't even finish typing that in without getting an error.

The only way I can get it to work is by doing this:

var temp = a.property1;
print ('the thing I want to see in the console is: $temp');

I haven't found the answer online... and me thinks there must be a way to just do it directly without having to create a variable first.

It seems you can also do this, but it doesn't seem to be documented anywhere:

print('..... $a.$property1');

You need to enclose the property in curly braces:

print('the thing I want to see in the console is: ${a.property}');

That will then print the value of a.property.
