decodeBoxConstraints static method
Decodes the given value
into a BoxConstraints. If the value is null
then null
will be returned. Otherwise, this expects a Map like value
that in JSON would look like:
{
"maxHeight": <double>,
"maxWidth": <double>,
"minHeight": <double>,
"minWidth": <double>
}
Implementation
static BoxConstraints? decodeBoxConstraints(
dynamic value, {
bool validate = true,
}) {
BoxConstraints? result;
if (value is BoxConstraints) {
result = value;
} else if (value != null) {
assert(SchemaValidator.validate(
schemaId: '$_baseSchemaUrl/box_constraints',
value: value,
validate: validate,
));
result = BoxConstraints(
maxHeight: JsonClass.parseDouble(value['maxHeight'], double.infinity)!,
maxWidth: JsonClass.parseDouble(value['maxWidth'], double.infinity)!,
minHeight: JsonClass.parseDouble(value['minHeight'], 0)!,
minWidth: JsonClass.parseDouble(value['minWidth'], 0)!,
);
}
return result;
