Using generic methods

Initially, Dart’s generic support was limited to classes.A newer syntax, called generic methods, allows type arguments on methods and functions:

T first<T>(List<T> ts) {
  // Do some initial work or error checking, then...
  T tmp = ts[0];
  // Do some additional checking or processing...
  return tmp;
}

Here the generic type parameter on first (<T>)allows you to use the type argument T in several places:

• In the function’s return type (T).
• In the type of an argument (List<T>).
• In the type of a local variable (T tmp).
