InputFile class

This class is used to represent a file to be sent.

Currently we have three ways to send a file:

  1. Use the file id.
  2. Use the file path.
  3. 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);

Constructors
