Querying

Flusmic uses the Predicate query browser to make all the requests.

This is how a simple query looks like:

final response = await flusmic
    .query([Predicate.at(DefaultPredicatePath.type, 'value')]);

Predicates

You can add as many predicates as you need in a single query call.

final response = await flusmic
    .query([Predicate.at(DefaultPredicatePath.type, 'value'),
        Predicate.at(DefaultPredicatePath.id, 'value')]);

Available predicates

Query

• Any
• At
• FullText
• Geopoint.Near
• GreaterThan
• Has
• In (into)
• InRange
• LessThan
• Missing
• Not
• Similar

Date and time

• After
• Before
• Between
• Day-of-month
• Day-of-month After
• Day-of-month Before
• Day-of-week
• Day-of-week After
• Day-of-week Before
• Month
• Month After
• Month Before
• Year
• Hour
• Hour After
• Hour Before

Predicate Paths

You need to declare a Predicate Path to tell Flusmic what type of Predicate you are using. There are two type:

DefaultPredicatePath

• Document: A Predicate to search by document
• Id: A predicate to search by document ID
• Tags: A predicate to search by tags in a document
• Type: A predicate to search by type in a document
• FirstPublicationDate: A predicate to search by created_at.
• LastPublicationDate: A predicate to search by updated_at.

CustomPredicatePath

final response = await flusmic
    .query([Predicate.at(CustomPredicatePath('custom-type', 'field'), 'value', fetch: false)]); 

If you will use a CustomPredicatePath with fetch o fetchLink query search, 'fetch' param must be true.

More info about how Predicates works in prismic.io query predicates API reference.

Graph Querying

Prismic.io has a way to work with GraphQL-like syntax called GraphQuery. We can make a request using the graphQuery() method. You can spect a FlusmicResponse after that:

final query = '''
  {
    test {
      title
    }
  }
  ''';
final graphResponse = await flusmic.graphQuery(query);
