Returns the integer value of the given environment declaration name
.
The result is the same as would be returned by:
int.tryParse(const String.fromEnvironment(name, defaultValue: "")) ?? defaultValue
Example:
const int.fromEnvironment("defaultPort", defaultValue: 80)
// The .fromEnvironment() constructors are special in that we do not want // users to call them using "new". We prohibit that by giving them bodies // that throw, even though const constructors are not allowed to have bodies. // Disable those static errors. //ignore: const_constructor_with_body //ignore: const_factory external const factory int.fromEnvironment(String name, {int defaultValue});
