// This is a simple example to show how to use the run_it package.
// It demonstrates the use of run, runOn, let, isNull, isNotNull, and ifNotNull methods.
// The example includes basic operations with integers and demonstrates how to handle null checks.
// Note: The last part of the example with dynamic map is intentionally left to show a potential issue with dynamic types.
// It is recommended to use known types to avoid runtime errors.
// This example is for demonstration purposes only and may not be suitable for production use.
// Make sure to run this example in a Dart environment where the run_it package is available.
// For more information, refer to the run_it package documentation.
