letBoolOrNull function

bool? letBoolOrNull(dynamic input)

Converts input to bool, returning Null on failure.

int 0/int 1 map to false/true to interoperate with SQLite (and other drivers) that store booleans as INTEGER. Any other integer value returns null rather than collapsing — bool(2) is not a meaningful truthiness anywhere in this codebase.

Supported types:

• String
• bool
• int (0 or 1 only)

Implementation

bool? letBoolOrNull(dynamic input) {
  if (input is bool) return input;
  if (input is String) {
    return bool.tryParse(input.trim(), caseSensitive: false);
  }
  if (input is int) {
    if (input == 1) return true;
    if (input == 0) return false;
  }
  return null;
}
