4.0.1

• Fixed a typo in the CHANGELOG.md file

4.0.0

• BREAKING: the EgyptianFraction class is not public anymore, it's been hidden in the internals of the package. The reason is that an egyptian fraction is not a kind of fraction but it's a way of representing a fraction: the EgyptianFraction type may be misleading (and it should have been called EgyptianFractionConverter since the beginning). The migration is very easy:

// Old code
EgyptianFraction(
  fraction: Fraction(5, 8),
).compute(); // [1/2 + 1/8]

EgyptianFraction.fromMixedFraction(
  mixedFraction: MixedFraction(2, 4, 5),
).compute(); // [1 + 1 + 1/2 + 1/4 + 1/20]

// New code
Fraction(5, 8).toEgyptianFraction(); // [1/2 + 1/8]
MixedFraction(2, 4, 5).toEgyptianFraction(); // [1 + 1 + 1/2 + 1/4 + 1/20]

• Added the Rational abstract supertype of Fraction and MixedFraction, which also adds the tryParse method:

// If the string is valid, it either returns a 'Fraction' or a 'MixedFraction'
Rational.tryParse('2/5');   // 2/5;
Rational.tryParse('2 4/5'); // 2 4/5;

// If the string is invalid, it returns 'null'
Rational.tryParse('/5');    // null
Rational.tryParse('');      // null

1.2.1

• Fixed some health suggestions.

1.2.0

• Removed Flutter dependencies.
• Fixes on documentation and examples.
