We like using program elements to add structure—providing opportunities for variation, reuse, or just having more helpful names. But sometimes the structure isn’t needed. It may be a function that’s named the same as its body code reads, or a class that is essentially one simple function.
What is a lazy class?
What is a code smell in programming?
What is Lazy class code smell?
Lazy Class smells represent classes that are under-used. If a class is rarely used, it can impede development by increasing the complexity of the codebase. Such a class might be unnecessary, and it’s functionality could be made a part of another class. Lazy Class is the opposite code smell to Large Class.
What is DART Lazy?
Lazy initialization is now part of dart from the release 2.12. Simply add late modifier to the variable declaration. late MyClass obj = MyClass(); And this object will be initialized only when it is first used.
What is lazy class?
The idea of Lazy class is simple – initialize class with action that builds or gets lazy loaded value and when value is asked then run the action if lazy loading is not happened yet.
Why is it called spaghetti code?
While it’s not clear who coined the term “spaghetti code” or when, it was being used to describe a tangled mess of code lacking structure by the late 1970s. In the 80s, the term was used at least once in a whitepaper to describe the model of code and fix that led to the development of waterfall programming.
What is lazy element?

What is primitive obsession?
Primitive Obsession is a code smell in which primitive data types are used excessively to represent your data models. Primitives are the basic data types available in most languages. For example, a string could represent a name, an address, or even an ID. The problem with primitives is they are very general.
What’s late in Flutter?
Overview. In Dart, we use the late keyword to declare variables that will be initialized later. These are called non-nullable variables as they are initialized after the declaration. Hence, we use the late keyword.
What is a future Flutter?
A Future class permits you to run work asynchronously to let loose whatever other threads ought not to be obstructed. Like the UI thread. In this blog, we will Explore Futures In Flutter. We will see how to use the future in your flutter applications.
What is Lazy Java?
The concept of delaying the loading of an object until one needs it is known as lazy loading. In other words, it is the process of delaying the process of instantiating the class until required.
What is messy code called?
Spaghetti code is a pejorative phrase for unstructured and difficult-to-maintain source code. Spaghetti code can be caused by several factors, such as volatile project requirements, lack of programming style rules, and software engineers with insufficient ability or experience.
What was Java originally called?
But yes, the original name for the programming language Java was Oak.
What is lazy class code smell?

Such a class might be unnecessary, and it’s functionality could be made a part of another class. Lazy Class is the opposite code smell to Large Class.
Is Lazy T thread safe?
By default, Lazy<T> objects are thread-safe. That is, if the constructor does not specify the kind of thread safety, the Lazy<T> objects it creates are thread-safe.
What is large class code smell?
Large Class code smell refers to the classes that tend to centralize the intelligence of the system. Large Class indicates weaknesses in design that can possibly slow down the development or increase the chance of failures in the future. In addition, it makes the system more difficult to understand, read and develop.
What is Dart lazy?
Lazy initialization is now part of dart from the release 2.12. Simply add late modifier to the variable declaration. late MyClass obj = MyClass(); And this object will be initialized only when it is first used.
What dispose Flutter?
Flutter – dispose() Method with Example
Dispose is a method triggered whenever the created object from the stateful widget is removed permanently from the widget tree. It is generally overridden and called only when the state object is destroyed.
What is a Future class?
Simply put, the Future class represents a future result of an asynchronous computation. This result will eventually appear in the Future after the processing is complete. Let’s see how to write methods that create and return a Future instance.
Is it good to learn Flutter?
Learning Flutter is worth it. Flutter is easy to learn and great for launching a career in mobile app development. Flutter also contributes to native app development and general mobile development on any iOS and Android device. Many development companies make use of Flutter.
