This PR removes the unnecessary dependency on the Material library from expansible_test.dart by replacing `MaterialApp` with `WidgetsApp`. Part of #177415 ### Changes 1. **Import change**: Replaced `package:flutter/material.dart` with `package:flutter/widgets.dart` 2. **Widget setup**: Changed from `MaterialApp(home: ...)` to `TestWidgetsApp(home: ...)` - `WidgetsApp` requires either `builder`, `onGenerateRoute`, or `pageRouteBuilder` to be provided If neither builder nor onGenerateRoute are provided, the pageRouteBuilder must be specified so that the default handler will know what kind of PageRoute transition to build. 3. **Updated position assertions**: Since `WidgetsApp` with `builder` doesn't include the default scaffold/status bar padding that `MaterialApp` with `home` provides, the expected y-coordinate values were adjusted by -34 pixels: - `90.08984375` → `56.08984375` - `98.0` → `64.0` - `80.91015625` → `46.91015625` - `48.0` → `14.0` ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
