TexImage class

A rendered image of LaTeX markup. The image is rendered asynchronously by a native web view.

TexImage(String math, {bool displayMode = true, Color? color, double? fontSize, Widget? placeholder, ErrorWidgetBuilder? error, AlignmentGeometry alignment = Alignment.center, bool keepAlive = true, Key? key})
const

Properties

alignment → AlignmentGeometry
Controls the alignment of the image within its bounding box; see Image.alignment.
final
color → Color?
color is the color of the rendered text.
final
displayMode → bool
displayMode is KaTeX's displayMode: math will be in display mode (\int, \sum, etc. will be large). This is appropriate for "block" display, as opposed to "inline" display. See also: https://katex.org/docs/options.html
final
error → ErrorWidgetBuilder?
A builder supplying a widget to display in case of error, for instance when math contains invalid or unsupported LaTeX syntax. By default it is Icons.error and the error message.
final
fontSize → double?
fontSize is the size in pixels of the rendered text. You can use e.g. TextStyle.fontSize as-is.
final
hashCode → int
The hash code for this object.
no setterinherited
keepAlive → bool
Whether or not the rendered image should be retained even when e.g. the widget has been scrolled out of view in a ListView.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
math → String
LaTeX markup to render. See here for supported syntax: https://katex.org/docs/supported.html
final
placeholder → Widget?
A widget to display while rendering. By default it is simply math as text.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<TexImage>
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.
