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

override

computeChildPositions() → List<int>

Compute children positions. Abstract.

inherited

computeChildren() → List<EquationRowNode>

Compute children. Abstract.

override

computeWidth() → int

Compute width from children. Abstract.

inherited

copyWith({EquationRowNode? functionName, EquationRowNode? argument}) → FunctionNode

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

inherited

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<EquationRowNode> newChildren) → FunctionNode

Return a copy of this node with new children.

override

wrapWithEquationRow() → EquationRowNode

Available on GreenNode, provided by the GreenNodeWrappingExt extension

Wrap a node in EquationRowNode

Operators

operator ==(Object other) → bool

The equality operator.
