Math class

Static, non-selectable widget for equations.

Sample usage:

Math.tex(
  r'\frac a b\sqrt[3]{n}',
  mathStyle: MathStyle.display,
  textStyle: TextStyle(fontSize: 42),
)

Compared to SelectableMath, Math will offer a significant performance advantage. So if no selection capability is needed or the equation counts on the same screen is huge, it's preferable to use Math.

Constructors

Math({Key? key, SyntaxTree? ast, MathStyle mathStyle = MathStyle.display, double? logicalPpi, OnErrorFallback onErrorFallback = defaultOnErrorFallback, MathOptions? options, ParseException? parseError, double? textScaleFactor, TextStyle? textStyle}): Math widget default constructor
const
Math.tex(String expression, {Key? key, MathStyle mathStyle = MathStyle.display, TextStyle? textStyle, OnErrorFallback onErrorFallback = defaultOnErrorFallback, TexParserSettings settings = const TexParserSettings(), double? textScaleFactor, MathOptions? options}): Math builder using a TeX string
factory

Properties

ast → SyntaxTree?: The equation to display.
final
hashCode → int: The hash code for this object.
no setterinherited
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
logicalPpi → double?: {@macro flutter_math_fork.math_options.logicalPpi}
final
mathStyle → MathStyle: Overriding MathOptions to build the AST.
final
onErrorFallback → OnErrorFallback: Fallback widget when there are uncaught errors during parsing or building.
final
options → MathOptions?: Overriding MathOptions to build the AST.
final
parseError → ParseException?: Errors generated during parsing.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
textScaleFactor → double?: Deprecated. Will be removed in a future version of Flutter. Use textScaler instead.
final
textStyle → TextStyle?: The style for rendered math analogous to Text.style.

Methods

build(BuildContext context) → Widget: Describes the part of the user interface represented by this widget.
override
createElement() → StatelessElement: Creates a StatelessElement to manage this widget's location in the tree.
