Implementation

const factory InlineKeyboardButton({
  /// Label text on the button
  @JsonKey(name: 'text') required String text,

  /// Optional. HTTP or tg:// url to be opened when button is pressed
  @JsonKey(name: 'url') String? url,

  /// of their chats, open that chat and insert the bot's username and the
  /// specified inline query in the input field. Can be empty, in which case
  /// just the bot's username will be inserted.
  ///
  /// Note: This offers an easy way for users to start using your bot in
  /// inline mode when they are currently in a private chat with it.
  /// Especially useful when combined with switch_pm… actions – in this case
  /// the user will be automatically returned to the chat they switched from,
  /// skipping the chat selection screen.

  /// the same chat – good for selecting something from multiple options.
