describeMismatches function

String describeMismatches(List<ResolutionMismatch> mismatches)

A report naming each drifted package, why the fixture's lock governs, and the repair.

Implementation

String describeMismatches(List<ResolutionMismatch> mismatches) {
  if (mismatches.isEmpty) return '';
  final buffer = StringBuffer()
    ..writeln(
      '${mismatches.length} package(s) resolve differently in the '
      'fixture than in the package it exercises.',
    )
    ..writeln(
      'The fixture reaches that package by `path:`, which supplies its '
      'SOURCE but not its RESOLUTION — so the fixture compiles the '
      "host's current lib/ against these older versions, and the error "
      'surfaces inside a directory the fixture does not own.',
    );
  for (final mismatch in mismatches) {
    buffer.writeln('  - $mismatch');
  }
  buffer.write('Repair: `dart pub get` in the fixture(s) named above.');
  return buffer.toString();
