Dart string

String

You should avoid using braces when you don't need to.

If you just insert a simple identifier and there is no other text at the end of that {} can delete it.

// good
'Hi, $name!'
"Wear your wildest $decade's outfit."
'Wear your wildest ${decade}s outfit.'

// bad
'Hi, ${name}!'
"Wear your wildest ${decade}'s outfit."
