DO use curly braces for all flow control structures.

Doing so avoids the dangling else problem.

BAD:

if (overflowChars != other.overflowChars)
  return overflowChars < other.overflowChars;

GOOD:

if (isWeekDay) {
  print('Bike to work!');
} else {
  print('Go dancing or read a book!');
}

There is one exception to this: an if statement with no else clause where the entire if statement (including the condition and the body) fits in one line. In that case, you may leave off the braces if you prefer:

GOOD:

if (arg == null) return defaultValue;

If the body wraps to the next line, though, use braces:

GOOD:

if (overflowChars != other.overflowChars) {
  return overflowChars < other.overflowChars;
}

要启用 curly_braces_in_flow_control_structures 规则，请在你的 analysis_options.yaml 文件中，在 linter > rules 下添加 curly_braces_in_flow_control_structures ：

linter:
  rules:
    - curly_braces_in_flow_control_structures
