pubup 0.2.2

Automatically update pubspec.yaml dependency constraints to the latest resolvable versions across Dart and Flutter workspace packages.

example/example.dart

// ignore_for_file: avoid_print

/// Example: using pubup programmatically.
///
/// This example demonstrates how to use the library API to discover workspace
/// packages, check for outdated dependencies, and collect update candidates
/// — all without modifying any files (equivalent to `--dry-run`).
///
/// Run from a Dart or Flutter project root:
///
/// ```bash
/// dart run example/example.dart
/// ```
