Readonly propsStatic Optional contextIf set, this.context will be set at runtime to the current value of the given Context.
Usage:
type MyContext = number
const Ctx = React.createContext<MyContext>(0)
class Foo extends React.Component {
static contextType = Ctx
context!: React.ContextType<typeof Ctx>
render () {
return <>My context's value: {this.context}</>;
}
}
Gets or sets the brush to use to fill the range.
Gets or sets the value at which the range ends along the scale.
Gets or sets the distance from the center of the gauge (from 0 to 1) at which to end rendering the inner sweep of the range. Values further from zero than 1 can be used to make this extend further than the normal radius of the gauge.
Gets or sets the distance from the center of the gauge (from 0 to 1) at which to start rendering the inner sweep of the range. Values further from zero than 1 can be used to make this extend further than the normal radius of the gauge.
Gets or sets the name of the range.
Gets or sets the distance from the center of the gauge (from 0 to 1) at which to end rendering the outer sweep of the range. Values further from zero than 1 can be used to make this extend further than the normal radius of the gauge.
Gets or sets the distance from the center of the gauge (from 0 to 1) at which to start rendering the outer sweep of the range. Values further from zero than 1 can be used to make this extend further than the normal radius of the gauge.
Gets or sets the outline to use when rendering the range.
Gets or sets the value at which the range starts along the scale.
Gets or sets the stroke thickness to use when rendering this range's outline.
Optional UNSAFE_Called immediately before mounting occurs, and before Component#render.
Avoid introducing any side-effects or subscriptions in this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
16.3, use componentDidMount or the constructor instead
Optional UNSAFE_Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.
Calling Component#setState generally does not trigger this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
16.3, use static getDerivedStateFromProps instead
Optional UNSAFE_Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState here.

16.3, use getSnapshotBeforeUpdate instead
Optional componentOptional componentCalled immediately after updating occurs. Not called for the initial render.
The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.
Optional componentCalled immediately before mounting occurs, and before Component#render.

Optional getRuns before React applies the result of render to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before render causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.
Static _create
If using the new style context, re-declare this in your class to be the
React.ContextTypeof yourstatic contextType. Should be used with type annotation or static contextType.
