Features #

  • Can be scaled upto any size within parent widget boundaries
  • Smooth animations with mathematically pre-derived ellipse path equation
  • Transparent background for flexible usage with colors
  • 3 electron orbits (support for more may come later)
  • Orbits angle can be changed
  • Orbits color can be changed (support for individual color may come later)
  • Orbits width can be changed
  • Nucleus size can be changed
  • Nucleus color can be changed
  • Electrons color can be changed (support for individual color may come later)
  • Individual electron's revolution duration can be changed
  • Any widget can be added in the center instead of nucleus

Getting Started #

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  create_atom: ^2.1.0-nullsafety

In your library add the following import:

import 'package:create_atom/create_atom.dart';

After that run flutter pub get

For help getting started with Flutter, view the online documentation.

Usage #

...
child: Atom(
  size: 100.0,
),
...

Yeah, just like that.

  • All properties are optional except size property.
  • You will get a black atom by default.

centerWidget property usage -

Assign centerWidget with any widget to display that Widget instead of nucleus.

...
child: Atom(
  size: 100.0,
  centerWidget: Text("At Center"),
),
...

Note: If both nucleusColor and centerWidget are set then the centerWidget will get preference.
