InputFile class
This class is used to represent a file to be sent.
Currently we have three ways to send a file:
- Use the file id.
- Use the file path.
- Use the file url.
The InputFile class has three separate constructors for each of these methods.
For example, if you want to send a file using the file id, you can use the InputFile.fromFileId constructor.
// Simply create an InputFile using the file id.
var photo = InputFile.fromFileId('file_id');
// Then pass the InputFile to the method that requires a file.
bot.sendPhoto(chatId, photo);
