ReplyPreview constructor
const
ReplyPreview({})
textTruncated defaults to false and revision and mediaCount to 0,
so a locally derived preview (a parent already in the loaded window)
needs only the fields it has.
Implementation
const ReplyPreview({
required this.id,
required this.conversationId,
required this.senderId,
this.text,
this.textTruncated = false,
required this.createdAt,
this.revision = 0,
this.mediaCount = 0,
});
