setDouble static method

Future<bool> setDouble(
  1. String? key,
  2. double? value
)

Saves a double value to persistent storage in the background. Android doesn't support storing doubles, so it will be stored as a float. Returns false if key is null.

Implementation

static Future<bool> setDouble(String? key, double? value) async {
  if (key == null || value == null) {
    return false;
  }
  final prefs = await instance;
  return prefs.setDouble(key, value);
}
