Input predictable on Flutter

Whenever a user provides input, there should be no change of context. Example of changing context include, but are not limited to: automatically submitting data, opening a new screen or moving to another element. Input should have predictable effects.

Input predictable - Flutter

In Flutter, be careful when using onChanged callbacks. Do not trigger a change of context when text changes.

Dart

TextField(
  onChanged: (text) {
    // Do not change context
  },
),
