WebA Dart library contains constants, functions, properties, exceptions, and typedefs, and set of classes. Importing a library To work with the library, we must import it into the current program. The Dart provides the import keyword, which is used to make the library available in the current file. We can use multiple libraries in a single file. Webfunctionpow. Returns x to the power of exponent. If x is an int and exponent is a non-negative int, the result is an int, otherwise both arguments are converted to doubles first, and the result is a double. For integers, the power is always equal to the mathematical result of x to the power exponent, only limited by the available memory.
