setDouble 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 the platform implementation can definitively determine that storing the preference failed. A return value of true indicates either that the value was written successfully, or that the underlying platform API does not report success or failure.

Implementation

Future<bool> setDouble(String key, double value) => _setValue('Double', key, value);
