  "message": "Add useLogicalPixels to ResizeImage for logical pixel cache sizing (#184549)\n\nfix https://github.com/flutter/flutter/issues/56239\n\nAdd `useLogicalPixels` to `ResizeImage` and `useLogicalCacheSize` to\n`Image.{network, file, asset, memory}` and `FadeInImage.{memoryNetwork,\nassetNetwork}` constructors.\n\nWhen `true`, the cache dimensions are interpreted as logical pixels\nrather than physical pixels, so the cached resolution follows the\nsurrounding device pixel ratio without requiring `BuildContext` at the\ncall site. Default is `false`; existing callers are unaffected.\n\n\u003cimg width\u003d\"300\" alt\u003d\"example\"\nsrc\u003d\"https://github.com/user-attachments/assets/43c10cd6-8b8e-4c87-93fd-b2be80030af2\"\n/\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eapp(lib/main.dart)\u003c/summary\u003e\n\n```dart\nimport \u0027package:flutter/material.dart\u0027;\n\nvoid main() \u003d\u003e runApp(const MyApp());\n\nclass MyApp extends StatelessWidget {\n  const MyApp({super.key});\n\n  @override\n  Widget build(BuildContext context) {\n    return MaterialApp(home: const MyWidget());\n  }\n}\n\nclass MyWidget extends StatelessWidget {\n  const MyWidget({super.key});\n\n  @override\n  Widget build(BuildContext context) {\n    final dpr \u003d MediaQuery.devicePixelRatioOf(context);\n    const url \u003d\n        \u0027https://images.unsplash.com/photo-1550613097-fe6c2c321cd3\u0027\n        \u0027?auto\u003dformat\u0026fit\u003dcrop\u0026w\u003d1200\u0026q\u003d80\u0027;\n\n    return Scaffold(\n      appBar: AppBar(title: Text(\u0027devicePixelRatio: $dpr\u0027)),\n      body: Center(\n        child: Column(\n          spacing: 8,\n          children: [\n            const Text(\u0027No cacheWidth (reference)\u0027),\n            Image.network(url, width: 300, fit: BoxFit.cover),\n            const Text(\u0027cacheWidth: 300, useLogicalCacheSize: false\u0027),\n            Image.network(url, width: 300, fit: BoxFit.cover, cacheWidth: 300),\n            const Text(\u0027cacheWidth: 300, useLogicalCacheSize: true\u0027),\n            Image.network(\n              url,\n              width: 300,\n              fit: BoxFit.cover,\n              cacheWidth: 300,\n              useLogicalCacheSize: true,\n            ),\n          ],\n        ),\n      ),\n    );\n  }\n}\n```\n\n\u003c/details\u003e\n\n## Pre-launch Checklist\n\n- [x] I read the [Contributor Guide] and followed the process outlined\nthere for submitting PRs.\n- [x] I read the [AI contribution guidelines] and understand my\nresponsibilities, or I am not using AI tools.\n- [x] I read the [Tree Hygiene] wiki page, which explains my\nresponsibilities.\n- [x] I read and followed the [Flutter Style Guide], including [Features\nwe expect every widget to implement].\n- [x] I signed the [CLA].\n- [x] I listed at least one issue that this PR fixes in the description\nabove.\n- [x] I updated/added relevant documentation (doc comments with `///`).\n- [x] I added new tests to check the change I am making, or this PR is\n[test-exempt].\n- [x] I followed the [breaking change policy] and added [Data Driven\nFixes] where supported.\n- [x] All existing and new tests are passing.\n\nIf you need help, consider asking for advice on the #hackers-new channel\non [Discord].\n\n**Note**: The Flutter team is currently trialing the use of [Gemini Code\nAssist for\nGitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code).\nComments from the `gemini-code-assist` bot should not be taken as\nauthoritative feedback from the Flutter team.
