When adding a flash card, the answer cannot be blank. (Shown in the upper part of the screenshot)
However, when editing the flash card, the user can set the answer to blank. (Shown in the lower part of the screenshot)
If the program does not allow empty answer, it should implement the check while the user edit the flash card as well.
