How to Initialize Variables in Constructor Body In Dart

A constructor is a special type of method that is called when you create a new instance of a class. The constructor is responsible for initializing the state of the object.

In Dart, you can initialize variables in the constructor body by 3 methods.

• Init a variable’s value on the declaration
• Use a semi-colon to assign values to variables
• Use late keyword

class Task {
    String title = '';
    String description = '';

    Task(this.title, this.description) {

    }
}

class Task {
    String title = '';
    String description = '';

    Task(this.title, this.description) {

    }
}

class Task {
    String title;
    String description;

    Task(this.title, this.description) : title = 'Daily task',  description = 'Need to finish today'{

    }
}

class Task {
    late String title;
    late String description;

    Task(this.title, this.description){
        title = 'Fix Flutter errors';  
        description = '';
    }
}
