Suggests removing unnecessary blocks ({ ... }).

Blocks that do not introduce a variable that shadows an existing variable are usually unnecessary. Consider removing such blocks to reduce code nesting.

Example

❌ Bad:

void fn() {
  // LINT: Avoid unnecessary code block. Try removing this block to reduce nesting.
  {
    print('hi');
  }
}

✅ Good:

void fn() {
  print('hi');

  final value = 1;

  {
    final value = 2; // Correct, there is another variable with the same name
  }
}
