compareVersions static method

bool compareVersions(String v1, String v2)

Compares two semantic versions.

v1 - The first version to compare v2 - The second version to compare Returns true if v1 is newer than v2.

Implementation

static bool compareVersions(String v1, String v2) {
  final parts1 = v1.split('.');
  final parts2 = v2.split('.');

  final minLength =
      parts1.length < parts2.length ? parts1.length : parts2.length;

  for (int i = 0; i < minLength; i++) {
    // Remove non-numeric parts (e.g., "-beta")
    final num1Part = parts1[i].split('-')[0];
    final num2Part = parts2[i].split('-')[0];

    final num1 = int.tryParse(num1Part) ?? 0;
    final num2 = int.tryParse(num2Part) ?? 0;

    if (num1 > num2) return true;
    if (num1 < num2) return false;
  }

  // Check if it's a pre-release
  final isPrerelease1 = v1.contains('-');
  final isPrerelease2 = v2.contains('-');

  // Official releases are always newer than pre-releases
  if (!isPrerelease1 && isPrerelease2) return true;
  if (isPrerelease1 && !isPrerelease2) return false;

  // If the version numbers are the same, consider the one with more segments as newer
  return parts1.length > parts2.length;
