isFractionGlyph property
bool
isFractionGlyph
Returns true
if this Fraction object has an associated unicode glyph.
For example:
Fraction(1, 2).hasUnicodeGlyph; // true
The above returns true
because "1/2" can be represented as ½, which is
a valid 'unicode glyph'.
Implementation
bool get isFractionGlyph => _valuesToGlyphs.containsKey(this);
