avoid-shadowed-extension-methods
preset: recommended
Warns when an extension declares a method with the name that is already used by the extension target.
If the extension target already has a method with the same name, it requires additional hacks to call the method from the extension. Consider renaming the method instead.
Example
❌ Bad:
extension Extension on String {
void split(String pattern) {} // LINT
}
✅ Good:
extension Extension on String {
void customSplit(String pattern) {}
}
