This updates Flutter Web to ignore copy/paste/selections if `enableInteractiveSelection` is `false` in a text field. Part of https://github.com/flutter/flutter/issues/157611 ## Scenarios tested 1. Click/tap on text: cursor should not move. 2. Double click/tap on text: text should not be selected 3. Triple click/tap on text: text should not be selected 4. Move cursor back (`Left arrow`): cursor should move back 5. Move cursor forward (`Right arrow`): cursor should move forward 8. Select previous word (`Shift+Left arrow`): text should not be selected, cursor moves to previous word 9. Select previous word (`Shift+Right arrow`): text should not be selected, cursor moves the next word 7. Select all shortcut (`Ctrl+A` or `Apple+A`): text should not be selected. ⚠️ With this fix, Flutter Web moves the cursor to the end of the text field. 8. Copy shortcut (`Ctrl+C` or `Apple+C`): clipboard should not be updated 9. Paste shortcut (`Ctrl+V` or `Apple+V`): clipboard should not be pasted 10. Right-click > Copy: clipboard should not be updated 11. Right-click > Paste: clipboard should not be pasted ## Browsers tested macOS: Chrome, Firefox, Safari ## Example app ```dart import 'package:flutter/material.dart'; void main() { runApp( MaterialApp( home: Scaffold( body: SafeArea( child: TextField( enableInteractiveSelection: false, ), ), ), ), ); } ``` ## 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.
