Lines 163 to 183 in 8f8a316

	bool _shouldUpdate(String? packageVersion, String? storeVersion) {
	if (packageVersion == storeVersion) return false;
	final arr1 = packageVersion!.split('.');
	final arr2 = storeVersion!.split('.');
	for (int i = 0; i < math.min(arr1.length, arr2.length); i++) {
	int? v1 = int.tryParse(arr1[i]);
	int? v2 = int.tryParse(arr2[i]);
	if (v1 == null || v2 == null) {
	if (arr2[i].compareTo(arr1[i]) > 0) {
	return true;
	}
	} else if (v2 > v1) {

	return false;
	}

Line 177 - 178 is faulty. This will return true when storeVersion is 5.1.1 and packageVersion is 6.0.0.

My fix will convert the given version from a string to an integer. Such that '6.0.0' will be 600 and '5.1.1' will be 511. Then comparing the 2 integers we can identify the latest version.
