matchesPattern function

bool matchesPattern(String path, String pattern)

Simple glob pattern matching for file exclusion.

Converts a glob-style pattern to a regular expression and tests it against the given file path. Supports common wildcards:

• * matches any characters
• ? matches a single character
• / is escaped for path matching

If the pattern is invalid regex, falls back to literal string matching.

path: File path to test against the pattern. pattern: Glob pattern (e.g., "/test/", "*.generated.dart").

Returns true if the path matches the pattern.

Example:

matchesPattern('lib/test/helper.dart', '**/test/**')  // true
matchesPattern('lib/main.dart', '**/test/**')        // false

Implementation

bool matchesPattern(String path, String pattern) {
  // Convert simple glob pattern to regex
  final regexPattern = pattern
      .replaceAll('*', '.*')
      .replaceAll('?', '.')
      .replaceAll('/', r'\/');

  try {
    final regex = RegExp(regexPattern);
    return regex.hasMatch(path);
  } on Object catch (_) {
    // If pattern is invalid, treat as literal string match
    return path.contains(pattern);
  }
}
