How to Create a Multi-User Blog Platform in FlutterFlow

Create a posts collection with fields: authorId (String), title (String), body (String, markdown formatted), excerpt (String, first 150 characters), coverImageUrl (String), category (String), tags (String Array), status (String: draft or published), publishedAt (Timestamp), viewCount (int, default 0), readTimeMinutes (int), commentCount (int, default 0). Create a comments subcollection under each post: userId (String), displayName (String), body (String), timestamp (Timestamp).

Create an AuthorDashboard page. Add a Backend Query filtering posts where authorId equals the current user ID. Display results in a ListView. Each row shows: title, status badge (green for published, grey for draft), viewCount, commentCount, publishedAt date, and action buttons for Edit and Delete. Add a floating action button labeled New Post that navigates to the PostEditor page. Add a TabBar at the top with All, Drafts, and Published tabs that filter the list by status.

Build a PostEditor page accepting an optional postId Route Parameter for editing existing posts. Add a TextField for title, a multiline TextField for the markdown body (at least 8 lines visible), a FlutterFlowUploadButton for cover image, a DropDown for category selection from an Option Set (Tech, Business, Lifestyle, Science, Other), and a Wrap widget with TextFields for adding tags. Add two buttons: Save Draft (sets status to draft and saves) and Publish (sets status to published, sets publishedAt to now). When editing, pre-fill all fields from the existing post document.

Create a BlogFeed page. Add a Backend Query on posts where status equals published, ordered by publishedAt descending. Display in a ListView. Each post card shows: cover image (Image widget), title (Text, Headline Small), excerpt (Text, Body Medium, max 2 lines), author name and avatar (Row with CircleImage and Text), publishedAt date, readTimeMinutes, and a category chip. Add a search TextField at the top that filters posts where title contains the search term. Add ChoiceChips for category filtering. Tapping a card navigates to PostDetail with the postId.

On the PostDetail page, load the post document by postId. Display the cover image full-width, title, author info row, publishedAt and readTimeMinutes, then the body rendered inside a flutter_markdown Custom Widget that handles headings, bold, italic, links, images, and code blocks. Below the content, add a Comments section: Backend Query on the post's comments subcollection ordered by timestamp descending, displayed in a ListView. Each comment shows displayName, body, and relative timestamp. Add a TextField and Send button pinned at the bottom to submit new comments. On comment creation, increment the post's commentCount using FieldValue.increment(1).

7  final String markdownText;
8  final double width;
9  final double height;

11  const MarkdownRenderer({
12    required this.markdownText,
13    required this.width,
14    required this.height,
15  });

17  @override
18  Widget build(BuildContext context) {
19    return SizedBox(
20      width: width,
21      child: MarkdownBody(
22        data: markdownText,
23        selectable: true,
24        onTapLink: (text, href, title) {
25          if (href != null) launchUrl(Uri.parse(href));
26        },
27      ),
28    );
29  }
30}

On PostDetail page load, increment the post's viewCount field using a Backend Call with FieldValue.increment(1). On the AuthorDashboard, add summary stats at the top: total views across all posts, total comments, and number of published posts. Use Backend Queries with aggregation or a Custom Function that sums the values. Optionally add a Cloud Function that calculates weekly view trends and stores them for chart display.
