Details
#DON'T explicitly catch Error
or types that implement it.
Errors differ from Exceptions in that Errors can be analyzed and prevented prior to runtime. It should almost never be necessary to catch an error at runtime.
BAD:
try {
somethingRisky();
} on Error catch(e) {
doSomething(e);
}
GOOD:
try {
somethingRisky();
} on Exception catch(e) {
doSomething(e);
}
