      [web] Pass creation params to the platform view factory (#128146) · b0188cd1
      Mouad Debbar authored 
      This concludes step 1 of the `HtmlElementView` improvements. It's now possible to pass creation params to platform view factories directly from `HtmlElementView`.

Here's a sample app using a single factory to render platform views in different colors:

  <summary>Code sample</summary>
  
  ```dart
import 'dart:js_interop';
import 'dart:ui_web' as ui_web;
import 'package:flutter/material.dart';
import 'package:web/web.dart' as web;

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Platform View Demo',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Platform View Demo'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: [
              BoxWrapper('red'),
              BoxWrapper(null),
              BoxWrapper('blue'),
            ],
          ),
        ),
      ),
    );
  }
}

bool isRegistered = false;

class BoxWrapper extends StatelessWidget {
  const BoxWrapper(this.cssColor);

  final String? cssColor;

  void register() {
    if (isRegistered) return;
    isRegistered = true;

    ui_web.platformViewRegistry.registerViewFactory('my-platform-view', (
      id, {
      Object? params,
    }) {
      params as String?;

      final element = web.document.createElement('div'.toJS) as web.HTMLElement;
      element.textContent = 'Platform View'.toJS;
      element.style
        ..lineHeight = '100px'.toJS
        ..fontSize = '24px'.toJS
        ..backgroundColor = (params ?? 'pink').toJS
        ..textAlign = 'center'.toJS;
      return element;
    });
  }

  @override
  Widget build(BuildContext context) {
    register();
    return SizedBox(
      width: 200,
      height: 100,
      child: Card(
        child: HtmlElementView(
          viewType: 'my-platform-view',
          creationParams: cssColor,
        ),
      ),
    );
  }
}
  ```

      [flutter_tools] cache flutter sdk version to disk (#124558) · 3246808c
      Christopher Fujino authored 
      Fixes https://github.com/flutter/flutter/issues/112833

Most of the actual changes here are in [packages/flutter_tools/lib/src/version.dart](https://github.com/flutter/flutter/pull/124558/files#diff-092e00109d9e1589fbc7c6de750e29a6ae512b2dd44e85d60028953561201605), while the rest is largely just addressing changes to the constructor of `FlutterVersion` which now has different dependencies.

This change makes `FlutterVersion` an interface with two concrete implementations:

1. `_FlutterVersionGit` which is mostly the previous implementation, and
2. `_FlutterVersionFromFile` which will read a new `.version.json` file from the root of the repo

The [`FlutterVersion` constructor](https://github.com/flutter/flutter/pull/124558/files#diff-092e00109d9e1589fbc7c6de750e29a6ae512b2dd44e85d60028953561201605R70) is now a factory that first checks if `.version.json` exists, and if so returns an instance of `_FlutterVersionFromGit` else it returns the fallback `_FlutterVersionGit` which will end up writing `.version.json` so that we don't need to re-calculate the version on the next invocation.

`.version.json` will be deleted in the bash/batch entrypoints any time we need to rebuild he tool (this will usually be because the user did `flutter upgrade` or `flutter channel`, or manually changed the commit with git).
