create_atom 2.1.0-nullsafety

An animated widget that displays atom with three electrons revolving around a nucleus at its center.

[2.1.0-nullsafety] - 2020-12-20

• This version is a stable nullsafety release but dart's nullsafety is still in preview so you have to make changes to your app/package in which you are going to use it.

• package -

  • Added two new customization properties - nucleusRadiusFactor and orbitsWidthFactor
  • One minor nullsafety fix

• example app -

  • Updated app with new properties
  • Background color can also be changed now
  • Minor nullsafety fixes

[2.0.0-nullsafety.0] - 2020-12-16

• package -

  • Migrated to NullSafety

• example app -

  • Migrated to NullSafety

[2.0.0] - 2020-06-13

• package -

  • Now the Atom's stack uses flutter's painter library implementation to draw the atom and its animations.
  • Painter library uses Skia graphics renderer to render graphical entities, so performance boosted by a factor 10 !
  • Some size and scaling factors slightly reduced.
  • Reduced many widgets in the Atom's build implementation to make it more performant.
  • Heavy code-refactor and reduced LOC.
  • Implemented dual EaseInOut curve in a single curved path using CatmullRomCurve.
  • Tried my best to mimic the original EaseInOut curve for both halves of the electron path.
  • You can find more details here - https://api.flutter.dev/flutter/animation/CatmullRomCurve-class.html.

• example app -

  • Updated example app with centerWidget property and other v2 changes.
  • App demo is now live at - http://abhi011999.github.io/create_atom_flutter/.

[1.4.0] - 2020-04-25 (BREAKING CHANGE)

• package -

  • Replaced scale property with size property by implementing new logic of creating atom stack.

    For users below v1.4.0 - Replace scale property with size in your corresponding code and set the value of size in accordance with this example -

    • If suppose scale is 1.0 then size will be 215.0 * 1.0 = 215
    • If suppose scale is 0.3 then size will be 215.0 * 0.3 = 64.5 Because 215.0 was hard-coded value by default.

  • Fixed centerWidget scaling issue, now it scales with the atom

  • Added extensive code documentation

  • Re-factored and re-structured the libraries

• example app -

  • Updated app with the breaking change

[1.3.0] - 2020-04-21

• package -

  • Added a new centerWidget property and feature
  • Corrected orbit angles in degrees
  • Fixed orbits scale clipping above 2.0x
  • Electron paths are now dynamically updated when the parent widget updates

• example app -

  • Added a new playground mode (web support will be added soon)

[1.2.0] - 2020-04-10

• Added example app for demonstration
• Updated documentation
• Removed un-used test file (tests can be added in future)

[1.1.0] - 2020-04-10

• Added documentation and example project.

[1.0.0] - 2020-04-09

• Initial release, go create some atoms !!
