|
The System class is a grab-bag of functionality exposed by the VM, mostly for
|
||
|
|
use during development or debugging.
|
||
|
|
|
||
|
|
## Static Methods
|
||
|
|
|
||
|
|
### System.**print**()
|
||
|
|
|
||
|
|
Prints a single newline to the console.
|
||
|
|
|
||
|
|
### System.**print**(object)
|
||
|
|
|
||
|
|
Prints [object] to the console followed by a newline. If not already a string,
|
||
|
|
the object is converted to a string by calling `toString` on it.
|
||
|
|
|
||
|
|
:::dart
|
||
|
|
System.print("I like bananas") // Prints "I like bananas".
|
||
|
|
|
||
|
|
### System.**printAll**(sequence)
|
||
|
|
|
||
|
|
Iterates over [sequence] and prints each element, then prints a single newline
|
||
|
|
at the end. Each element is converted to a string by calling `toString` on it.
|
||
|
|
|
||
|
|
:::dart
|
||
|
|
System.printAll([1, [2, 3], 4]) // Prints "1[2, 3]4".
|
||
|
|
|
||
|
|
### System.**write**(object)
|
||
|
|
|
||
|
|
Prints a single value to the console, but does not print a newline character
|
||
|
|
afterwards. Converts the value to a string by calling `toString` on it.
|
||
|
|
|
||
|
|
:::dart
|
||
|
|
System.write(4 + 5) // Prints "9".
|
||
|
|
|
||
|
|
In the above example, the result of `4 + 5` is printed, and then the prompt is
|
||
|
|
printed on the same line because no newline character was printed afterwards.
|
||
|
|
|
||
|
|
### System.**clock**
|
||
|
|
|
||
|
|
Returns the number of seconds (including fractional seconds) since the program
|
||
|
|
was started. This is usually used for benchmarking.
