Feedback Card

The Feedback Card is designed to display messages with an associated status, making it ideal for showing system feedback, success messages, warnings, or errors.

Initializer

To create a Feedback Card in ESP-DASH v5, use the dash::FeedbackCard<T> class. T can be dash::string, const char*, etc.

dash::FeedbackCard<const char*> feedback(dashboard, "Status");
feedback.setFeedback("Light is ON", dash::Status::SUCCESS);

The status can be one of the following:

• dash::Status::NONE — No status set (default).
• dash::Status::INFO — Indicates informational messages.
• dash::Status::SUCCESS — Indicates a successful operation.
• dash::Status::WARNING — Indicates a warning condition.
• dash::Status::DANGER — Indicates a critical error or failure.
