  • Then you have to download from the internet (e.g. from Pixabay or Unsplash) the flag of that country and upload it to the MIT APP Inventor platform through the element called flag, in the Picture property.
  • Next you should find out how to spell the name of the country in English and how to say leave and press me in the language of that country.
