How can I use Reflection (Mirrors) to access the method names in a Dart Class?

Question

I need to "fetch" the methods in a Dart Class.

How can I do this?

And I want to be able to call the methods.

May I see an example?

Answer 1

Here's an easy copy-pasteable code sample:

import 'dart:mirrors';
import 'dart:io';

main() {
  var im = reflect(new File('test')); // Retrieve the InstanceMirror of some class instance.
  im.type.methods.values.forEach((MethodMirror method) => print(method.simpleName));
}

Output is:

existsSync
_delete
exists
directory
_getDecodedLines
readAsTextSync
readAsBytesSync
readAsLinesSync
_directory
throwIfError
lastModifiedSync
readAsLines
open
_ensureFileService
deleteSync
delete
_exists
length
openInputStream
create
_create
readAsText
_openStdioSync
openOutputStream
_fullPath
_lastModified
fullPathSync
readAsBytes
lastModified
_openStdio
_open
openSync
lengthSync
directorySync
fullPath
createSync
_lengthFromName
