Why writing case consistently and following naming conventions is important in all programming language?

Every developer should know how the naming conventions help to make the code more readable, maintainable, organized, and of higher quality.

  • Code readability: Consistent naming conventions make code easier to read and understand, both for the original author and for other developers who may work on the code in the future.
  • Code maintainability: Following conventions makes it easier to maintain the code, especially in larger projects, as it provides a clear and predictable structure.
  • Code organization: Consistent naming helps to organize code and makes it easier to find specific classes, functions, and variables.
  • Collaboration: Consistent naming conventions make it easier for multiple developers to work on the same codebase, as everyone knows what to expect from the names used.
  • Code quality: Following naming conventions and best practices can also improve the overall quality of code and make it easier to debug and test.

Class names: UpperCamelCase, starting with a capital letter. 

For example:
class MyClassName {
  // class body

Function names: lowerCamelCase, starting with a lowercase letter.

For example:
void myFunctionName() {
  // function body

File names: snake_case and should match the name of the main class defined in the file, with a .dart extension. 

For example, if the main class is named MyClassName, the file should be named my_class_name.dart.

Variable names: lowerCamelCase, starting with a lowercase letter. 

For example:
int myVariable;

Object names: lowerCamelCase, starting with a lowercase letter. 

For example:
MyClassName myObject = MyClassName();

It's worth noting that these naming conventions are guidelines, and the most important thing is to be consistent throughout your codebase.
