call method

P call(Param value)

Create a provider from an external value.

That external value should be immutable and preferably override ==/hashCode. See the documentation of Provider.family for more informations.

Implementation

P call(Param value) {
  return _cache.putIfAbsent(value, () {
    final provider =
        create(value, builder, name == null ? null : '$name ($value)');
    assert(
      provider._from == null,
      'The provider created already belongs to a Family',
    );
    return provider
      .._from = this
      .._argument = value;
  });
}
