Switch statements in Dart offer a clear and structured way to control program flow by mapping specific values to corresponding actions. This is especially useful when you have a set of possible commands or options, such as user inputs, and you want to perform different actions depending on each command. Instead of writing multiple if-else statements, you can use a switch to make your intent more obvious and your code easier to read.

For example, imagine you are building a simple command-line tool that responds to user commands like "start", "stop", or "pause". With a switch statement, you can map each of these commands directly to the appropriate action.

Using a switch statement like the one above makes your code much clearer than using a series of if-else statements. Each command is mapped to its action in a straightforward way, so it is easy to see what happens for each possible input. This reduces the chance of mistakes and makes it simpler to add or change commands in the future. The structure of the switch statement also signals to readers that you are handling a fixed set of options, rather than evaluating a series of unrelated conditions.

Dart 3 introduces pattern matching in switch statements, which allows you to match not just on specific values but also on types and structures, such as tuples. Pattern matching makes your code more expressive and safer by letting you destructure data directly in the case labels and handle more complex conditions without extra code. In the previous example, you can see how pattern matching enables you to respond differently based on both the type and content of the input, providing a flexible and powerful tool for controlling flow in your programs.
