When working with collections in Dart, such as lists, you'll often encounter the need to find the maximum and minimum values within them. Dart provides several convenient ways to achieve this efficiently. Let's explore some tricks to accomplish these tasks effectively.

Finding the Maximum Value

[[See Video to Reveal this Text or Code Snippet]]

In this example, reduce(max) iterates through the list and compares each element to determine the maximum value efficiently.

Finding the Minimum Value

Similarly, you can find the minimum value using reduce with min from dart:math.

Here, reduce(min) traverses the list to identify the smallest element.

Custom Comparisons

In this case, the custom function passed to reduce compares Person objects based on their age property to find the oldest person.

Handling Edge Cases

When working with empty lists or lists of null values, be mindful of potential null or empty checks to avoid runtime errors.
