RetryWidget class

RetryWidget Class Documentation

The RetryWidget class is a Flutter widget that provides a user-friendly way to display an error message along with a retry button. It is commonly used to prompt users to retry an action that previously failed, such as network requests or form submissions.

Constructors:

  • RetryWidget({Key? key, Function()? onPressed, String? message, String? label}): Constructs an instance of RetryWidget with optional parameters.

Properties:

  • onPressed: A callback function that is executed when the retry button is pressed. It typically triggers the action that needs to be retried.

  • message: An optional string message that describes the error or reason for the retry.

  • label: An optional label for the retry button. The default label is "Try Again."

Widgets:

The RetryWidget consists of the following widgets:

  • A text widget displaying the error message in red text if provided.

  • A material button with a red background for retrying the action. The button label defaults to "Try Again."

Usage Example:

RetryWidget(
  onPressed: () {
    // Retry the action here.
  },
  message: 'Failed to load data. Please try again.',
)

Parameters:

  • onPressed: A function that will be called when the retry button is pressed. It is typically used to trigger the action that needs to be retried.

  • message: An optional string message that describes the error or reason for the retry. If provided, it will be displayed in red text above the retry button.

  • label: An optional string label for the retry button. If not provided, the default label "Try Again" will be used.

Use Case:

Use the RetryWidget in your UI when you want to give users the option to retry an action that has failed, such as reloading data after a network error or resubmitting a form after validation errors.
