SpanBuilder class

given some plain text, e.g.: "The quick brown fox" allows you to apply multiple spans at multiple positions. Positions can be specified by word, that is e.g. "brown" or range (from=10, to=15) and spans are subclasses of InlineSpan Once you are done using SpanBuilder, use build to return calculated list of spans. The rest of the text, that has no span either inherits TextStyle from parent span or can be forced to use defaultStyle

USAGE:

final spans = SpanBuilder("The quick brown fox")
  .apply(TextSpan(text: "brown", style: TextStyle(fontWeight: FontWeight.bold)))
  .apply(TextSpan(text: "🦊"), whereText: "fox")
  .build()
