Functions
assignBandLanes ({required List <LayrzCalendarEntry entries , required DateTime rangeStart , required DateTime rangeEnd → LayrzCalendarLaneAssignments
Packs entries into stable lane indices for the date range
rangeStart..rangeEnd inclusive, so overlapping multi-day bars within
AllDayBand never collide.
assignLanes ({required List <LayrzCalendarEntry entries , required DateTime monthAnchor → LayrzCalendarLaneAssignments
Packs entries into stable lane indices for the month containing
monthAnchor, so overlapping multi-day bars never collide and a
continuous event never changes lane between week rows.
assignOverlapColumns (List <LayrzCalendarEntry entries → List <TimedEventPlacement
Packs entries into evenly split overlap columns for one day's timed
hour grid.
avatarBackgroundFor (LayoEmotion emotion → Color
Resolves the fixed avatar background color for a given LayoEmotion .
avatarRingFor (LayoEmotion emotion → Color
Resolves the fixed avatar ring color for a given LayoEmotion : a
darkened shade of that same emotion's own avatarBackgroundFor , by
_kAvatarRingDarkenFactor, so every avatar reads as "background with a
deeper-tone-of-the-same-color ring" rather than a ring color that clashes
against a differently-hued background.
buildLayrzUiL10nDelegates (Iterable <LocalizationsDelegate ?userDelegates → List <LocalizationsDelegate
Combines caller-supplied localizations delegates with the default LayrzUiL10nDelegate .
findAllTextOccurrences (String haystack , String needle , {required bool caseSensitive → List <TextRange
Finds every non-overlapping occurrence of needle within haystack,
returning each as a TextRange expressed in haystack's own (original
case) offsets.
findRenderTextSources (RenderObject root → List <RenderTextSource
Walks the live render tree rooted at root, collecting a
RenderTextSource for every RenderParagraph and RenderEditable found,
in depth-first traversal order.
formatHourLabel (int hour , LayrzTimeFormat format , LayrzUiL10n l10n → String
Formats hour (0–23) as an hour-axis label under format.
formatLayrzProgressValue (double value , int decimals → String
Formats a determinate progress fraction as a percentage string, biasing
away from the two endpoints when rounding would misrepresent them.
formatLayrzShortcut (Set <LogicalKeyboardKey ?keys , {LayrzPlatform ?platform → String
Formats a keyboard shortcut for display, using platform-native key names and glyphs.
formatStrftime (DateTime dateTime , String pattern , LayrzUiL10n l10n → String
Formats dateTime according to pattern, a strftime-style format string
using Python datetime directives (%Y, %m, %d, %H, %I, %M,
%S, %y, %B, %b, %A, %a, %p, %j, %%) — not
intl/Dart DateFormat patterns (yyyy-MM-dd). This mirrors the old
layrz_theme pickers' own pattern: '%Y-%m-%d' convention, so consumers
migrating from layrz_theme keep their existing format strings unchanged —
one of the few places this batch preserves the old API rather than
breaking it.
installFindKeyCapture ({required VoidCallback onFindPressed → FindKeyCapture
No-op on non-web targets: there is no browser document to intercept a
keydown on, and no native find-in-page dialog to suppress in the first
place — Ctrl/Cmd+F on desktop/mobile is handled entirely by the Flutter
focus-based LayrzShortcut path (see lib/src/keyboard/), which this file
does not touch.

Converts a slider value within [min, max] to a fraction in [0.0, 1.0].
mimeTypeForExtension (String ?extension → String
Resolves the MIME type for a lowercase file extension (without the
leading dot), falling back to application/octet-stream when the
extension is unrecognized or null.
orderedWeekdayLabels (LayrzUiL10n l10n , int firstDayOfWeek → List <String
Returns the seven localized weekday display labels from l10n, ordered to
start at firstDayOfWeek, via orderedWeekdays .
orderedWeekdays (int firstDayOfWeek → List <int
Returns the seven DateTime weekday constants (DateTime.monday through
DateTime.sunday), rotated so firstDayOfWeek is first.
parseStrftimePattern (String pattern → List <StrftimeToken
Parses pattern into a flat list of StrftimeToken s.
positionDelegate (LayrzPreferredSide position → TooltipPositionDelegate
Computes the position delegate for RawTooltip based on the desired position.
quantizeLayrzSliderValue ({required double value , required double min , required double max , required int ?divisions → double
Quantises value to the nearest one of divisions equally-spaced steps
between min and max, then clamps the result back into [min, max].
registerWebFont ({required String family , required String url → Future <void >
No-op on non-web targets: there is no DOM to register a @font-face with.
registerWebFontFromBytes ({required String family , required ByteData bytes → Future <void >
No-op on non-web targets: there is no DOM to register a @font-face with.
resolveFoldSplit ({required List <DisplayFeature features , required Rect shellRect , double minPaneExtent = 120.0 , double minSplitHeight = kLayrzFoldMinSplitHeight → LayrzFoldSplit ?

Resolves the track and thumb colours for a LayrzSlider frame from its
current interaction state, following the precedence documented on
LayrzCheckboxInput/LayrzSwitchInput: disabled > error > pressed
(including an active drag) > hover/focused > default .
resolveRenderTextSource (Rect targetGlobalRect , List <RenderTextSource sources → RenderTextSource ?
Finds the best RenderTextSource in sources to resolve word-level
geometry for a semantics match whose whole-node box is targetGlobalRect,
or null when nothing in sources plausibly backs that match.
resolveWordHighlights ({required FindMatch match , required String query , required List <RenderTextSource sources , bool caseSensitive = false → MatchHighlight
Resolves the highlight geometry to paint for match, given the query text
that produced it and every text-bearing render object currently in the
tree (sources, as returned by findRenderTextSources in
render_text_walker.dart).
sameZoneDate (DateTime reference , int year , int month , [int day = 1 → DateTime
Builds a date-only DateTime for year/month/day, in the same zone
reference itself is expressed in.
sameZoneDateTime (DateTime reference , int year , int month , int day , [int hour = 0 , int minute = 0 , int second = 0 , int millisecond = 0 , int microsecond = 0 → DateTime
Builds a full date+time DateTime for the given fields, in the same zone
reference itself is expressed in — see sameZoneDate for the subtype
preservation rule, the Duration-vs-calendar-field-stepping rule, and why
no package:timezone initialization is needed.
timedEventBlock (BuildContext context , {required DateTime date , required TimedEventPlacement placement → Widget
Renders one timed event block positioned by placement within date's
24-row hour grid.
titleWeightedBodyStyle (LayrzTokens tokens → TextStyle
Composes LayrzTokens.typography 's body size with title's emphasis
for the month grid's structural text (the weekday header row and each
day-of-month number).
walkSemantics (SemanticsNode root , String query , {bool caseSensitive = false , bool includeHidden = true , Set <int excludeSubtreeRootIds = const {} → List <FindMatch
Walks the semantics tree rooted at root, collecting every node whose
text contains query as a substring, and returns them as FindMatch es
ordered in reading order (top-to-bottom, then left-to-right).
Typedefs

The signature shared by PageRouteBuilder 's transitionsBuilder and
go_router's CustomTransitionPage.transitionsBuilder.
LayrzTreeNodeBuilder T >
= Widget Function(BuildContext context , LayrzTreeNode <T > node , int depth , bool isExpanded , bool isLeaf , bool isSelected , bool isPartiallySelected , VoidCallback ?onToggle , VoidCallback ?onSelect
Signature for a function that builds the Widget representing a single
row of a LayrzTreeView or LayrzSliverTreeView .
