A Flutter package that is used to create trim path animation on given path.

Features

• start point tween
• end point tween
• offset tween
• Support non-continuous path

Showcase

Usage

• AnimatedPath widget is used to animated path for given animation.

AnimatedPath(
    animation: animationController.view,
    path: Path()
    ..moveTo(100, 100)
    ..relativeLineTo(400, 0)
    ..relativeLineTo(0, 400)
    ..relativeLineTo(-400, 0)
    ..relativeLineTo(0, -400),
    paint: paint,
    start: Tween(begin: 0.0, end: 0.7),
    end: Tween(begin: 0.0, end: 1.0),
    offset: Tween(begin: 0.0, end: 0.3),
)

• Provide initial and final value of start, end or offset for the path.

For e.g.

Tween(begin: 0.0, end: 1.0)

This will put the start of the path at (0.0 * pathLength) (initially) and at (1.0 * pathLength) when animation finishes path for values between 0 and 1 (inclusive) will be visible only However, one can provide values < 0 or > 1 for different animation sync effects.

Similarly, for end and offset.

• Values for end is calculated based on tween provided should always be greater than start at any point of time, or path will not be visible.

• offset value for given animation is added in both start and end valued for path.

• For a constant value use ConstantTween.

• Works for continuous and non-continuous path both.
