flutter sort list

someObjects.sort();

// By object property value
someObjects.sort((a, b) => a.someProperty.compareTo(b.someProperty));

// To reverse sort, just swab a and b
someObjects.sort((a, b) => b.someProperty.compareTo(a.someProperty));

flutter dart sort list of objects

objects.sort((a, b) {
  return a.value['name'].toString().toLowerCase().compareTo(b.value['name'].toString().toLowerCase());
});
To reverse it you could do b.someProperty.compareTo(a.someProperty). Or sort it and then use .reversed

dart list sort by value

someObjects.sort((a, b) => a.someProperty.compareTo(b.someProperty));

sort list dart

List<int> nums = [13, 2, -11];
nums.sort();
print(nums);  // [-11, 2, 13]
