Functions

convertKeyboardMoveSelection(InlineSpan text, TextSelection selection) → TextSelection
convertKeyboardMoveTextPostion(InlineSpan text, TextPosition? textPosition) → TextPosition?
convertTextInputPostionToTextPainterPostion(InlineSpan text, TextPosition textPosition) → TextPosition
convertTextInputSelectionToTextPainterSelection(InlineSpan text, TextSelection selection) → TextSelection
convertTextPainterPostionToTextInputPostion(InlineSpan text, TextPosition? textPosition, {bool? end}) → TextPosition?
convertTextPainterSelectionToTextInputSelection(InlineSpan text, TextSelection selection, {bool selectWord = false}) → TextSelection

correct caret Offset make sure caret is not in text when caretIn is false
getInlineOffset(InlineSpan inlineSpan) → int
Walks this text span and its descendants in pre-order and calls visitor for each span that has text.
handleSpecialTextSpanDelete(TextEditingValue value, TextEditingValue? oldValue, InlineSpan oldTextSpan, TextInputConnection? textInputConnection) → TextEditingValue
hasSpecialText(InlineSpan textSpan) → bool
hasT<T>(InlineSpan? textSpan) → bool
joinChar(InlineSpan value, Accumulator offset, String char) → InlineSpan
join char into text
makeSureCaretNotInSpecialText(InlineSpan text, TextPosition textPosition) → TextPosition
textSpanToActualText(InlineSpan textSpan) → String

PaintBackground = bool Function(BackgroundTextSpan backgroundTextSpan, Canvas canvas, Offset offset, TextPainter? painter, Rect rect, {Offset? endOffset, TextPainter? wholeTextPainter})
if you don't want use default, please return true. endOffset is the text top-right Offfset allTextPainter is the text painter of extended text. painter is current background text painter
