The ability to move applications to the microSD memory card is a feature of Android 2.2 so it goes without saying that you can definitely do this on the Samsung Dart.
Note: Not all Android Market applications support this feature. If the Move To SD Card button from step 3 is greyed out, it is not supported. Due to restrictions and conditions set solely by the application developer and not Samsung, the app must reside in internal memory.
