Output
Dart validation example 6 runs against sample input and produces a checkable result.
Line-by-line explanation
- Line 1 sets up the Dart validation example: const concept = "Dart validation";.
- Line 2 adds one required part of the working pattern: const task = { input: "sample", goal: "ship a useful feature" };.
- Line 3 exposes the output so you can verify the behavior: console.log(concept, task.goal);.
Why this example is useful
This example is useful because it isolates dart validation without surrounding noise, so you can see the idea clearly.
