Segment<T> class abstract

Represents a single node in a route tree.

T is the type of objects that get returned on routing to a path. It could be Widget or some kind of RouteHandler

Implementers

Constructors

Segment(SegmentParser parser, RouteBuilder<T>? create, RouteBuilder<T>? createError, List<Segment<T>> children)
Public default constructor called by implementing classes
Segment.param({required ParamParser parser, RouteBuilder<T>? create, List<Segment<T>> children, RouteBuilder<T>? createError})
Creates a Segment that matches a path segment using the parser and injects it into the ParseContext. Usually used with a UintParser.
factory
Segment.path({required String name, RouteBuilder<T>? create, List<Segment<T>> children, RouteBuilder<T>? createError})
Creates a path segment that matches a segment literally like /settings, /user, etc
factory
Segment.regExpParam({required RegExpParamParser parser, RouteBuilder<T>? create, List<Segment<T>> children, RouteBuilder<T>? createError})
Creates a Segment that matches a path segment against a regular expression and adds it to the ParseContext.
factory
Segment.regExpPath({required RegExp regExp, RouteBuilder<T>? create, List<Segment<T>> children, RouteBuilder<T>? createError})
Creates a Segment that matches a path segment against a regular expression.

Properties

children Iterable<Segment<T>>
no setter
create RouteBuilder<T>?
Creates an instance of T, called when the Segment that owns this callback is routed to.
final
createError RouteBuilder<T>?
If Segment.parse cannot find a matching route the bottom most createError is called instead.
final
hashCode int
The hash code for this object.
no setterinherited
parser SegmentParser
The parser that handles whether this Segment matches a route.
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
parse(ParseContext<T> context, Iterable<String> segments, RouteBuilder<T> createError) → Result<T, T>?
Returns a Result<T, T>? where null means this doesn't match the current path segment, Result.ok means a match was found and Result.err means an error was encountered trying to parse the path segments.
toString() String
A string representation of this object.

Operators

operator ==(Object other) bool
The equality operator.
