Available Methods

Constructor

Creates a ConversationPredicate

Constructor


1const ConversationPredicate({
2  FieldPredicate<ConversationAccessLevel>? access,
3  Map<String, CustomFieldPredicate>? custom,
4  bool? hasUnreadMessages,
5  NumberPredicate? lastMessageTs,
6  FieldPredicate<String?>? subject,
7});

NOTE: All the parameters passed to the constructor are also available as read-only properties of the constructed object.

Parameters

access

(optional): FieldPredicate<ConversationAccessLevel>?

Only select conversations that the current user as specific access to.

Example:


1// to remove conversations that the user has no access to anymore, do:
2access: FieldPredicate.notEquals(ConversationAccessLevel.none)

custom

(optional): Map<String, CustomFieldPredicate>?

Only select conversations that have particular custom fields set to particular values.

Every key must correspond to a key in the custom conversation data that you set (by passing custom to Conversation). It is not necessary for all conversations to have these keys.

Examples, assuming you have set a category custom field on your conversations:


1// only show conversations that have no category set:
2custom: { 'category': CustomFieldPredicate.notExists() }
3
4// only show conversations of category "shoes"
5custom: { 'category': CustomFieldPredicate.equals('shoes') }
6
7// only show conversations either category "shoes" or "sandals"
8custom: { 'category': CustomFieldPredicate.oneOf(['shoes', 'sandals']) }
9
10// only show conversations about shoes that are marked visible.
11// this assumes you also have a custom field called `visibility`
12custom: {
13  'category': CustomFieldPredicate.equals('shoes'),
14  'visibility': CustomFieldPredicate.equals('visible'),
15}

hasUnreadMessages

(optional): bool?

Set this field to only select conversations that have, or don't have any, unread messages.

lastMessageTs

(optional): NumberPredicate?

Only select conversations that have the last message sent in a particular time interval.

Example:


1// to show only the conversations that have the last message sent after the UNIX timestamp 1679298371586
2lastMessageTs: NumberPredicate.greaterThan(1679298371586)

subject

(optional): FieldPredicate<String?>?

Only select conversations that have the subject set to particular values.

Example:


1// to show only the conversations that have "Black leather boots" or "Hair Wax 5 Gallons" as the subject
2subject: FieldPredicate.oneOf(["Black leather boots", "Hair Wax 5 Gallons"])

class CompoundConversationPredicate

Allows you to filter conversations down to a specific subset.

Pass feedFilter to ConversationList.

For example, to match all the conversations to which you have read access, or whose custom "accountId" field has the "my_account" value, use the following:


1ConversationList(
2  feedFilter: CompoundConversationPredicate.any([
3    ConversationPredicate(
4      access: FieldPredicate.equals(ConversationAccessLevel.read),
5    ),
6    ConversationPredicate(
7      custom: {
8        'accountId': CustomFieldPredicate.equals('my_account'),
9      },
10    ),
11  ]),
12),

To show everything (that is, to disable the filter), use an empty object:


1ConversationList(
2  feedFilter: ConversationPredicate(),
3),

Available Methods

CompoundConversationPredicate.any

3),

To show all messages (ie disable the filter), just pass an empty object:


1ChatBox(
2  messageFilter: MessagePredicate(),
3),
