toBoolean function
Converts the string to a boolean.
In loose mode (the default) every value is true except '', '0'
and 'false'. In strict mode only '1' and 'true' are true and
everything else is false. Keyword matching is case-insensitive.
Example:
toBoolean('true'); // true
toBoolean('0'); // false
toBoolean('yes', strict: true); // false
Implementation
bool toBoolean(String str, {bool strict = false}) => _toBoolean(str, strict);
