## Description

The `_IndexedStackExampleState` class in the `IndexedStack` API example
creates a `TextEditingController` but never disposes it, causing a
resource leak.

Added a `dispose()` override that calls `fieldText.dispose()` before
`super.dispose()`.

```dart
@OverRide
void dispose() {
  fieldText.dispose();
  super.dispose();
}
```

Fixes #186324

## Tests

Existing tests in
`examples/api/test/widgets/basic/indexed_stack.0_test.dart` cover the
example. No new tests needed for a dispose fix.

…s outside lib (#183838)

Fix `toMultiRootPath` producing URIs with empty authority, breaking hot
restart for entrypoints outside `lib/`

When running `flutter run -d web-server` with an entrypoint outside
`lib/` (e.g. `integration_test/main.dart`), hot restart triggers but
code changes are never reflected. The app keeps showing stale code.

### Root cause

The hot restart pipeline has a URI format mismatch between two code
paths:

1. **`_generateEntrypoint`** (in `resident_web_runner.dart`) registers
the entrypoint with the compiler using the `Uri` constructor:
   ```dart
   Uri(scheme: 'org-dartlang-app', path: '/main.dart')
// produces: org-dartlang-app:/main.dart (no authority,
hasAuthority=false)
   ```

2. **`toMultiRootPath`** (in `compile.dart`) converts invalidated
`file:` URIs back to `org-dartlang-app:` URIs during recompilation using
string concatenation:
   ```dart
   '$scheme://${filePath.substring(fileSystemRoot.length)}'
// produces: org-dartlang-app:///main.dart (empty authority,
hasAuthority=true)
   ```

These two URIs are **not equal**, so the frontend server doesn't find a
matching library to invalidate and returns cached (stale) output.

This only affects entrypoints outside `lib/` because files under `lib/`
are converted to `package:` URIs via `packageConfig.toPackageUri()`,
bypassing `toMultiRootPath` entirely.

### Fix

Replace the string concatenation in `toMultiRootPath` with the `Uri`
constructor — the same approach used by `_generateEntrypoint`:

```dart
// Before (string concatenation — introduces empty authority):
return '$scheme://${filePath.substring(fileSystemRoot.length)}';

// After (Uri constructor — no authority):
return Uri(scheme: scheme, path: filePath.substring(fileSystemRoot.length)).toString();
```

Fixes #175318

The analyzer will start reporting cases where a super parameter could be
used, and the type of the supar parameter is tightened in the subclass
constructor. This is still a perfectly valid super parameter use case.

…nds (#186394)

Fixes #186393.

On pre-`#version 140` GL targets (`kOpenGLES`, `kOpenGLDesktop`),
SPIRV-Cross lowers `uniform Block { ... } instance;` to `struct Block {
... }; uniform Block instance;` and the driver reports members as
`instance.member`. `BufferBindingsGLES` looks them up by the **block**
name modulo a case- and underscore-insensitive match, so a
non-conforming instance name (e.g. `uniform ToonInfo { ... } toon;`)
silently binds every member to GL location `-1`.

This PR makes `impellerc` rewrite non-conforming instance names to
`_<BlockName>` (which reduces to the block name under the same fold)
before emitting GLSL for those targets. Conforming instance names
(`XInfo` / `x_info`) are left alone; shader reflection (keyed on the
block name) is untouched; no shader bundle / runtime stage format
change. Vulkan and Metal are unaffected (they bind by descriptor index).

Verified on a Pixel 10 Pro: the broken shader from the linked issue now
renders identically to Vulkan / Metal. New compiler unit test
(`UniformBlockInstanceNameCanonicalizedForGL`) compiles `mat2_test.frag`
(`uniform Params { ... } uParams;`) for the GL targets and asserts the
emitted source uses `_Params.` rather than `uParams.`.
