Unreleased

0.5.0 — 2021-3-9

• Added StringDiff.isEmpty and StringDiff.isNotEmpty.

• Added getSpans and getTypedSpans to SpanList.

• Added SpanController.getAppliedSpansWithUnsafeType.

• Fixed: GestureRecognizers on spans are now indexed with their attribute instead of the resolved attribute value, because function object equality does not work with inline lambdas.

• Fixed: SpannedTextEditingController.buildTextSpan did not translate composition indices, causing an exception in some cases with characters that take up multiple code units in UTF-16 (like most emoji).

• Changed: TextAttribute.resolve now takes a BuildContext instead of taking an AttributeTheme directly.

• Changed: made TextStyle in buildTextSpans optional.

0.4.0-0 — 2020-12-22

• Removed TextAttribute.simple. In favor of custom classes, so each attribute has its own type and serialization can use the type to determine which encoder to use.

• Changed: moved ExpandRules to be a part of attributes themselves.

0.3.0-0 — 2020-12-18

• Added system to theme TextAttributes with AttributeTheme.

• Added Range to avoid confusion with TextRange. TextRange is designed to be for indexing into String by UTF-16 code units.

• Changed: TextAttribute now has a resolve method that returns the actual information for applying the attribute in the form of TextAttributeValue.

• Changed: the characters library is used to index with grapheme clusters instead of UTF-16 code units. This changes most String-based API to use Characters instead.

• Changed: use Range in AttributeSpan and related classes to avoid confusion with UTF-16 indices used by TextRange.

• Changed: renamed SpanList.spans to iter to prevent confusing spans.spans.

• Changed: SpannedTextEditingController takes a SpanList now instead of Iterable<AttributeSpan>.

• Changed: renamed InsertBehavior to ExpandRule and FullInsertBehavior to SpanExpandRules. Finally, I've come up with the right name for this concept :)

• Changed: rename SpannedString() to SpannedString.chars() and let unnamed constructor take String.

• Fixed: Changed library name from flutter_span_controller to flutter_spanned_controller.

0.2.0-0 — 2020-12-14

• Added: SpannedStringBuilder to fluently build SpannedString.

0.1.1-0 — 2020-12-14

• Changed: Replaced template README with short explanation.

0.1.0-0 — 2020-12-11
