Are you looking to integrate a fully customizable timeline into your Flutter application? Look no further! This guide will walk you through the steps to utilize the Flutter Timeline Widget, offering you the ability to create real-world application references with ease.

What is the Flutter Timeline?

The Flutter Timeline Widget is a general-purpose timeline widget that allows developers to present events efficiently across multiple platforms, including Android, iOS, Web, macOS, Linux, and Windows. This widget boasts features such as:

• Fully customizable indicator dots
• Support for spacing between indicator dots and lines
• Seamless integration of events with connected lines
• Real-world demos for easy reference
• Support for anchor and global offsets
• Used in production applications by enterprises

Installation

To get started, you simply need to add the following dependency in your pubspec.yaml file:

dependencies:
  flutter_timeline: latest

Usage

Let’s break down the usage of the Flutter Timeline Widget with an analogy. Imagine you’re constructing a timeline of events for a history class. Each event is like a date on your timeline—think of them as the different items you need to add. You’d want to connect them with lines for clarity, just as you would in your application!

Simple Implementation Example

TimelineEventDisplay get plainEventDisplay {
    return TimelineEventDisplay(
      child: TimelineEventCard(
        title: Text("Just Now"),
        content: Text("Someone commented on your timeline ${DateTime.now()}"),
      ),
      indicator: TimelineDots.of(context).circleIcon,
    );
}

List events;

Widget _buildTimeline() {
    return TimelineTheme(
      data: TimelineThemeData(lineColor: Colors.blueAccent),
      child: Timeline(
        indicatorSize: 56,
        events: events,
      ),
    );
}

void _addEvent() {
    setState(() {
      events.add(plainEventDisplay);
    });
}

Here’s how this code works:

• TimelineEventDisplay: Think of this as a “box” representing an event on your timeline, which holds details like the title and content.
• _buildTimeline: This is like laying out your events on paper, applying styles to make it visually appealing.
• _addEvent: This function allows you to add new events dynamically—akin to adding more dates to your classroom timeline as you learn more!

Advanced Options

If you want to use offsets or anchors, consider this:

Widget _buildTimeline() {
    return Timeline(
      indicatorSize: 56,
      events: events,
      altOffset: Offset(0, -24) // Sets the offset
    );
}

TimelineEventDisplay get plainEventDisplay {
    return TimelineEventDisplay(
      anchor: IndicatorPosition.top,
      indicatorOffset: Offset(0, 24),
      child: TimelineEventCard(
        title: Text("Multi-line Title Awesome!"),
        content: Text("Someone commented on your timeline ${DateTime.now()}"),
      ),
      indicator: randomIndicator,
    );
}

Using offsets lets you change the position of the events on your timeline, much like adjusting the spacing on a classroom bulletin board for better visibility.

Troubleshooting

If you encounter any issues during integration, consider the following troubleshooting tips:

• Ensure all dependencies are correctly listed in pubspec.yaml.
• Run flutter pub get to fetch the new packages.
• If the timeline does not display, ensure your widget tree includes the Timeline correctly.
