Match a file's sole class or enum name to its snake-case basename.

Other declarations may coexist with the type. Files with multiple classes or enums, generated inner-dot suffixes, and part-of files are left alone. Naming convention violations themselves belong to the existing naming rules.

Invalid

example.dartdart
class Account {
  final int id;
  Account(this.id);
}
The sole class or enum `Account` does not match this filename. Rename the file to `account.dart` or rename the declaration to match the file.
1class Account {

Valid

example.dartdart
class Good {
  void run() {}
}

      "style": {
        "prefer-match-file-name": "error"
