Retrieve a message

You can retrieve a specific message in an open or group channel by creating and passing the MessageRetrievalParams object as an argument into the getMessage() method.

Note: Starting from Flutter Chat SDK 3.1.0, MessageRetrievalParams requires the channelType, channelUrl, and messageId parameters.

Dart

try {
    // Create a MessageRetrievalParams object.
    final params = MessageRetrievalParams(
        messageId: MESSAGE_ID
        channelType: ChannelType.open
        channelUrl: CHANNEL_URL
    );

    // Pass the params to the parameter of the getMessage() method.
    final message = await BaseMessage.getMessage(params);
    // The specified message is successfully retrieved.
} catch (e) {
    // Handle error.
}
