Methods

buildWidget(MathOptions options, List<BuildResult?> childBuildResults) → BuildResult
Compose Flutter widget with child widgets already built
override
computeChildOptions(MathOptions options) → List<MathOptions>
Calculate the options passed to children when given options from parent
inherited
encodeTeX({TexEncodeConf conf = const TexEncodeConf()}) → String

Available on GreenNode, provided by the TexEncoderExt extension

Encodes the node into TeX
expandEquationRow() → List<GreenNode>

Available on GreenNode, provided by the GreenNodeWrappingExt extension

If this node is EquationRowNode, its children will be returned. If not, itself will be returned in a list.
getRange(int pos) → TextRange
TextRange

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
shouldRebuildWidget(MathOptions oldOptions, MathOptions newOptions) → bool
Whether the specific MathOptions parameters that this node directly depends upon have changed.
override
toJson() → Map<String, Object?>
override
toString() → String
A string representation of this object.
inherited
unwrapEquationRow() → GreenNode

Available on GreenNode, provided by the GreenNodeWrappingExt extension

Return the only child of EquationRowNode
updateChildren(covariant List<GreenNode> newChildren) → LeafNode
