Using Dart's factory constructor feature to implement the singleton pattern
class MyClass {
static final MyClass _singleton = new MyClass._internal();
factory MyClass() {
return _singleton;
}
MyClass._internal() {
... // initialization logic here
}
... // rest of the class
}
// consuming code
MyClass myObj = new MyClass(); // get back the singleton
...
// another piece of consuming code
MyClass myObj = new MyClass(); // still getting back the singleton
