TimelineTile

A package to help build customisable timelines in Flutter.

Example

Some use cases:


Timeline Showcase
Football Timeline
Activity Timeline

Success Timeline
Delivery Timeline
Weather Timeline

Getting Started

A Timeline consists in a group of TimelineTiles. To build a tile you can simply use:

TimelineTile()

This will build a default tile that aligns to the left, with a height of 100:

Simple Timeline

There are 4 types of alignment.

  • TimelineAlign.left
  • TimelineAlign.right
  • TimelineAlign.center
  • TimelineAlign.manual

The left and right alignment allows a child in their opposite sides. On the other hand, both center and manual allows children on both sides. For example, one tile widh alignment to the center:

TimelineTile(
  alignment: TimelineAlign.center,
  rightChild: Container(
    constraints: const BoxConstraints(
      minHeight: 120,
    ),
    color: Colors.lightGreenAccent,
  ),
  leftChild: Container(
    color: Colors.amberAccent,
  ),
);

When providing children to the tile the height will be as minimum as possible, so you can control it with a height constraint (at least minHeight). This way the tile knows how to size it properly.

Centered Tile

Manual aligning the idicator

With TimelineAlign.manual you can provide the lineX, which allows you to specify a value from 0.0 to 1.0, that represents a widht percentage. For example, aligning at 30% of the widht:

TimelineTile(
  alignment: TimelineAlign.manual,
  lineX: 0.3,
  rightChild: Container(
    constraints: const BoxConstraints(
      minHeight: 120,
    ),
    color: Colors.lightGreenAccent,
  ),
  leftChild: Container(
    color: Colors.amberAccent,
  ),
);

Manual align indicator

Is it the first or the last?

You can decide if a tile is the first os the last in a timeline. This way you control whether a top or bottom line must be rendered.

First and last

See the implementation here

Start to make a timeline

You can finally start to combine some tiles to make a Timeline. The flag hasIndicator can control whether an indicator should or shouldn't be rendered.

Customize the indicator as you wish

The default indicator is a circle, and you can customize it as you wish. With IndicatorStyle you can change the color, the Y position based on values from 0.0 to 1.0 or give it a padding. You must explicitly provide its width though.

Custom indicator

Give an icon to the indicator

With IconStyle you can provide an Icon to be rendered inside the default indicator.

See the implementation here

Or provide your custom indicator

With the indicator parameter you can customize the tile with your own indicator. However, you must control its size through both width and height parameters.

Custom indicator

Customize the tile's line

With LineStyle you can customize both topLine and bottomLine.

Connect tiles with TimelineDivider

The TimelineDivider widget allows you to connect tiles that are aligned in different X axis, when combined with TimelineAlign.manual.
