What are the principles of naming methods in the Dart language?

In Dart language, methods are named according to the lowerCamelCase style, which means:

• The method name starts with a lowercase letter.
• Each subsequent word starts with an uppercase letter without separators.

For example:

void calculateSum() {
  // method body
}

String getUserName() {
  return 'User';
}

Methods are usually named with verbs or verb phrases that reflect the action they perform. This improves code readability and understanding.
