Quick summary of this article
This article demonstrates how to use a Dart switch case statement to handle different day-of-the-week values. The code assigns a string to a variable and then uses a switch to compare it against multiple case labels, printing a specific message for each day. It also includes a default clause to catch any invalid input.
- The switch statement evaluates the variable `day` and matches it against string case labels like 'Monday' and 'Friday'.
- Each case prints a unique message, such as "It's Monday, the start of the work week." for Monday.
- A `break` statement is used after each case to stop execution and avoid falling through to the next case.
- The `default` case handles any value that doesn't match the listed days, printing "Not a valid day."
- This structure provides a clean, readable way to execute different code blocks based on a single variable's value.
void main() {
String day = 'Monday';
switch (day) {
case 'Sunday':
print('It\'s Sunday, time to relax!');
break;
case 'Monday':
print('It\'s Monday, the start of the work week.');
break;
case 'Tuesday':
print('It\'s Tuesday, the second day of the work week.');
break;
case 'Wednesday':
print('It\'s Wednesday, middle of the week.');
break;
case 'Thursday':
print('It\'s Thursday, almost the weekend.');
break;
case 'Friday':
print('It\'s Friday, the end of the work week.');
break;
case 'Saturday':
print('It\'s Saturday, time to enjoy the weekend!');
break;
default:
print('Not a valid day.');
}
