updateFileContexts method

Future<bool> updateFileContexts(Set<String> filePaths)

Inform the analyzer that the provided filePaths have been updated.

Refreshes the Dart analysis context for the changed files and returns true if any of them are (or were) future call files, meaning code generation should run.

Implementation

Future<bool> updateFileContexts(Set<String> filePaths) async {
  // Only consider files within the tracked directory.
  final relevantPaths = filePaths
      .where((f) => p.isWithin(absoluteIncludedPaths, p.absolute(f)))
      .toSet();

  final errorsBefore = _fileCache.values.any((r) => r.hadErrors);
  final keysBefore = _fileCache.keys.toSet();

  await analyze(
    collector: CodeGenerationCollector(),
    changedFiles: relevantPaths,
  );

  final errorsAfter = _fileCache.values.any((r) => r.hadErrors);
  final keysAfter = _fileCache.keys.toSet();

  if (errorsBefore ||
      errorsAfter ||
      keysBefore.length != keysAfter.length ||
      keysAfter.difference(keysBefore).isNotEmpty) {
    return true;
  }

  for (final path in relevantPaths) {
    if (!path.endsWith('.dart') || path.endsWith('_test.dart')) continue;
    if (_fileCache.containsKey(path)) return true;
    if (_isFutureCallFile(File(path))) return true;
  }

  return false;
