TextSelection class - services library

Constructors

TextSelection({required int baseOffset, required int extentOffset, TextAffinity affinity = TextAffinity.downstream, bool isDirectional = false}): Creates a text selection.
const
TextSelection.collapsed({required int offset, TextAffinity affinity = TextAffinity.downstream}): Creates a collapsed selection at the given offset.
const
TextSelection.fromPosition(TextPosition position): Creates a collapsed selection at the given text position.

affinity → TextAffinity: If the text range is collapsed and has more than one visual location (e.g., occurs at a line break), which of the two locations to use when painting the caret.
final
base → TextPosition: The position at which the selection originates.
read-only
baseOffset → int: The offset at which the selection originates.
final
end → int: The next index after the characters in this range.
finalinherited
extent → TextPosition: The position at which the selection terminates.
read-only
extentOffset → int: The offset at which the selection terminates.
final
hashCode → int: The hash code for this object.
read-onlyoverride
isCollapsed → bool: Whether this range is empty (but still potentially placed inside the text).
read-onlyinherited
isDirectional → bool: Whether this selection has disambiguated its base and extent.
final
isNormalized → bool: Whether the start of this range precedes the end.
read-onlyinherited
isValid → bool: Whether this range represents a valid position in the text.
read-onlyinherited
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited
start → int: The index of the first character in the range.

copyWith({int? baseOffset, int? extentOffset, TextAffinity? affinity, bool? isDirectional}) → TextSelection: Creates a new TextSelection based on the current selection, with the provided parameters overridden.
expandTo(TextPosition position, [bool extentAtIndex = false]) → TextSelection: Returns the smallest TextSelection that this could expand to in order to include the given TextPosition.
extendTo(TextPosition position) → TextSelection: Keeping the selection's TextSelection.baseOffset fixed, pivot the TextSelection.extentOffset to the given TextPosition.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
inherited
textAfter(String text) → String: The text after this range.
inherited
textBefore(String text) → String: The text before this range.
inherited
textInside(String text) → String: The text inside this range.
inherited
toString() → String: A string representation of this object.
