How to use String format similar to NSString in Flutter?

How can I use a string format like this with Flutter? static let sampleText = “Stack Overflow is a user-oriented question and answer site about computer programming. Located within the Stack Exchange sites, Stack Overflow was founded in 2008 by %@ and %@” NSString(format: sampleText, Jeff Atwood, Joel Spolsky)

Something similar in Dart we have String interpolation: String name = 'John Doe'; int age = 30; String interpolated = 'My name is $name and I\'m $age years old.'; More examples: here
