total method

Expression<double> total({
  1. Expression<bool>? filter,
})

Calculate the sum of all non-null values in the group.

If all values in the group are null, total returns 0.0. This function uses floating-point values internally. To only consider rows matching a predicate, you can set the optional filter. Note that filter is only available from sqlite 3.30, released on 2019-10-04. Most devices will use an older sqlite version.

Implementation

Expression<double> total({Expression<bool>? filter}) =>
    _AggregateExpression('TOTAL', [this], filter: filter);
