GlyphHintCollector class
Walks the element tree once and returns the GlyphHints that intersect
interest (the rects of the nodes that can use them).
Release-safe by construction: every fact comes from a typed check (is Icon, is AssetImage, …), a field, or a guarded dynamic member read —
never from toString(), runtimeType names, or class-name strings, which
release builds strip (package:flutter, dart:ui) and --obfuscate
renames.
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
assetWords(
String path) → (String, String) -
Words from an asset path, plus its explicit on/off state suffix:
assets/nav/ic_home_active@2x.png→ (home,on). Returns ('', '') when what is left looks like a hash or an id rather than a name. -
collect(
{required List< Rect> interest, required double dpr, required String selfIdentifier}) → List<GlyphHint> -
iconName(
IconData icon) → String -
Icon name for
icon, keyed by (font family, code point) and built from Flutter's own constants — never a hardcoded code point. -
probe(
Object o, int member, Object? read(dynamic d)) → Object? -
svgAssetName(
Widget w) → String? -
SvgPicture.asset(...)'s asset name: flutter_svg 2.x keeps it onbytesLoader.assetName(SvgAssetLoader), 1.x onpictureProvider.assetName(ExactAssetPicture). Read dynamically — member access survives--obfuscate; class names do not. -
svgTint(
Widget w) → Object? -
svgUrl(
Widget w) → String? -
SvgPicture.network(...)'s URL (flutter_svg 2.xSvgNetworkLoader.url), read dynamically like svgAssetName.
Constants
- maxElements → const int
- Element visits after which the walk gives up and returns nothing. All or nothing on purpose: a partial walk could see one tab item's glyphs and not its siblings', which the odd-one-out would read as "selected".
