  "message": "Listen to text spacing overrides on the web (#178081)\n\nOriginal PR/Discussion: https://github.com/flutter/flutter/pull/172915\n\n# Framework:\n* `EditableText`/`SelectableText`, applies\n`lineHeightScaleFactorOverride`, `wordSpacingOverride`, and\n`letterSpacingOverride` to it\u0027s `TextStyle` similarly to how we already\ndo for bold platform overrides. Note `SelectableText` is built on\n`EditableText` so it also applies these overrides.\n* `Text`, applies `lineHeightScaleFactorOverride`,\n`wordSpacingOverride`, and `letterSpacingOverride` to it\u0027s `TextStyle`\nsimilarly to how we already do for bold platform overrides.\n* Exposes line height override through\n`MediaQueryData.lineHeightScaleFactorOverride` and\n`maybeLineHeightScaleFactorOverrideOf(context)`.\n* Exposes letter spacing override through\n`MediaQueryData.letterSpacingOverride` and\n`maybeLetterSpacingOverrideOf(context)`.\n* Exposes word spacing override through\n`MediaQueryData.wordSpacingOverride` and\n`maybeWordSpacingOverrideOf(context)`.\n* Exposes paragraph spacing override through\n`MediaQueryData.paragraphSpacingOverride` and\n`maybeParagraphSpacingOverrideOf(context)`.\n* `MediaQuery.applyTextStyleOverrides()` \\\n`MediaQueryData.applyTextStyleOverrides()` to be able to reset/override\nthe text spacing settings on `MediaQueryData`.\n\n# Engine:\n* Introduces new members on `PlatformDispatcher` API that hold the text\nspacing properties that are overridden on the web.\n* We provide the `lineHeightScaleFactorOverride`,\n`letterSpacingOverride`, `wordSpacingOverride`, and\n`paragraphSpacingOverride` on the web by attaching a `ResizeObserver` to\nan off-screen hidden element, when its size changes we capture its text\nspacing CSS properties, and notify the framework through\n`onMetricsChanged`.\n\nFixes #142712\n\n\nhttps://github.com/user-attachments/assets/aaaa3e74-c232-4956-acd2-ae1a4487e415\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 [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\n---------\n\nCo-authored-by: Renzo Olivares \u003croliv@google.com\u003e",
