This implements https://github.com/flutter/flutter/issues/132654#issuecomment-1738221257, namely:

Make `Chromium.close` more robust:

* Send `SIGTERM` and wait up to 5 seconds, if the process exited, great! Return from the function.
* If the process has not exited, then send a `SIGKILL`, which is a much firmer way to exit a process. Same as before, wait up to 5 seconds, if the process exited, great! Return from the function.
* If it still hasn't exited then give up trying to exit Chromium, just print a warning to the console and return from the function.

Bonus: a few nullability fixes and extra `-v` logging.

Resolves #128046.

Adds a services API that allows flutter app developers to write app code that determines `--flavor` the app was built with.

This is implemented by having the tool adding the value of `--flavor` to its list of dart environment declarations, which will be available to the app at run time. Specifically,`FLUTTER_APP_FLAVOR` is set. I chose this implementation for its simplicity. There is some precedent for this, but only for web ([example](https://github.com/flutter/flutter/blob/cd2f3f5e78409027d3c9014172708e4dec7f2185/packages/flutter_tools/lib/src/runner/flutter_command.dart#L1231)).

The issue https://github.com/flutter/flutter/issues/134644 has been closed, and the test has been passing for [50 consecutive runs](https://data.corp.google.com/sites/flutter_infra_metrics_datasite/flutter_check_test_flakiness_status_dashboard/?p=BUILDER_NAME:%22Windows%20module_custom_host_app_name_test%22).
This test can be marked as unflaky.

This PR fixes #134846. As discussed in the issue, the onSubmitted callback of a TextField is called when the browser switches tabs or is sent to the background if the flutter app is running in any mobile browser (desktop browsers are not affected). Furthermore there is no straight forward way to distinguish between onSubmitted being called because the user pressed the enter key and it being called because the user switched tabs. For example in a chat app this would cause a message to be sent when the user submits the text by pressing "send" on the virtual keyboard as well as when the user switches to another tab. The later action is likely not so much intended.

The next section explains what causes the bug and explains the proposed fix.

## Bug Analysis
The root cause for this behaviour is line 3494 in editable_text.dart: https://github.com/flutter/flutter/blob/0b540a87f1be9a5bb7e550c777dfe5221c53a112/packages/flutter/lib/src/widgets/editable_text.dart#L3487-L3499
Only if the app is running on the web `_finalizeEditing` is called and this will then trigger the onSubmitted callback. If flutter is running on the web, there are only exactly 3 cases, in which the function is called. The following call trace analysis will describe why.
  - `connectionClosed()` is only called by in one location, `_handleTextInputInvocation` of the TextInput service.
https://github.com/flutter/flutter/blob/367203b3011fc1752cfa1f51adf9751d090c94e6/packages/flutter/lib/src/services/text_input.dart#L1896C12-L1899
  - In particular it is only called if the TextInput service receives a 'TextInputClient.onConnectionClosed' message from the engine.
  - The only location where the web part of the engine send this message is the `onConnectionClosed` function of the TextEditingChannel.
https://github.com/flutter/engine/blob/cbda68a720904137ee9dfdf840db323afcf52705/lib/web_ui/lib/src/engine/text_editing/text_editing.dart#L2242-L2254
  - `onConnectionClosed` in turn is only called by the `sendTextConnectionClosedToFrameworkIfAny` function of `HybridTextEditing`.
https://github.com/flutter/engine/blob/cbda68a720904137ee9dfdf840db323afcf52705/lib/web_ui/lib/src/engine/text_editing/text_editing.dart#L2340-L2345

The function `sendTextConnectionClosedToFrameworkIfAny` is only called at 3 distinct locations of the web engine.

### 1. IOSTextEditingStrategy 
As described in the comment `sendTextConnectionClosedToFrameworkIfAny` is called if the browser is sent to the background or the tab is changed.
https://github.com/flutter/engine/blob/cbda68a720904137ee9dfdf840db323afcf52705/lib/web_ui/lib/src/engine/text_editing/text_editing.dart#L1632-L1656

### 2. AndroidTextEditingStrategy
Same situation as for iOS. `sendTextConnectionClosedToFrameworkIfAny` is also called if `windowHasFocus` is false, which is the case if the browser is sent to background or the tab is changed.
https://github.com/flutter/engine/blob/cbda68a720904137ee9dfdf840db323afcf52705/lib/web_ui/lib/src/engine/text_editing/text_editing.dart#L1773-L1785

### 3. TextInputFinishAutofillContext
This call seems to always happen when `finishAutofillContext` is triggered by the framework.
https://github.com/flutter/engine/blob/cbda68a720904137ee9dfdf840db323afcf52705/lib/web_ui/lib/src/engine/text_editing/text_editing.dart#L2075-L2083

## Proposed Fix
The fixed proposed and implemented by this PR is to simply delete the call to`_finalizeEditing` in the `connectionClosed` function of editable_text.dart.
https://github.com/flutter/flutter/blob/0b540a87f1be9a5bb7e550c777dfe5221c53a112/packages/flutter/lib/src/widgets/editable_text.dart#L3487-L3499

The reasoning for this being:
   * `_finalizeEditing` is only called in `connectionClosed` for the web engine.
   * As explained by the trace analysis above, the web engine only triggers this `_finalizeEditing` call in 3 cases.
   * In the 2 cases for IOSTextEditingStrategy and AndroidTextEditingStrategy the web engine triggering the call only causes the undesired behaviour reported in the issue.
   * In the third case for TextInputFinishAutofillContext, I can't see a good reason why this would require calling `_finalizeEditing` as it only instructs the platform to save the current values. Other platforms also don't have anything that would trigger onSubmitted being called, so it seems safe to remove it.
   * For other platforms the onConnectionClosed function was recently incorporated to only unfocus the TextField. So removing the call `_finalizeEditing` unifies the platform behaviour. See also

This change collapses the selection at the clicked/tapped location on single click down for desktop platforms, and on single click/tap up for mobile platforms to match native.

This is a change from how `SelectionArea` previously worked. Before this change a single click down would clear the selection. From observing a native browser it looks like when tapping on static text the selection is not cleared but collapsed. A user can still attain the selection from static text using the `window.getSelection` API.

https://jsfiddle.net/juepasn3/11/ You can try this demo out here to observe this behavior yourself. When clicking on static text the selection will change.

This change also allows `Paragraph.selections` to return selections that are collapsed. This for testing purposes to confirm where the selection has been collapsed.

Partially fixes: #129583

This is a tiny tweak to replace some top level if clauses with guard clauses in `FutureBuilder`. I find the resultant code much more readable, but this is a matter of taste and I didn't see any info one way or another on it in the style guide so let me know if this is not to your all's preference.

Fix `SearchAnchor`'s search view isn't updated when the theme changes & widgets inside the search view do not inherit local themes (#132749)

fixes [SearchAnchor (search view) UI glitch on platform brightness changes](https://github.com/flutter/flutter/issues/131835)
fixes [Search view widgets cannot inherit local themes](https://github.com/flutter/flutter/issues/132741) 

### Description

- This fixes an issue where the `SearchAnchor`'s search view isn't updated when the platform brightness changes.
- Fixes an issue where widgets inside the search view cannot use local themes

### Actual Results

`SearchAnchor` currently passed both global and local themes on the search view popup pushing and it uses anchor. button's context to look up the theme.

![search_view drawio (1)](https://github.com/flutter/flutter/assets/48603081/b5317fb1-ee73-461c-a119-f2a1e29f5909)

As a result, when the platform changes and the search view is rebuilt, it cannot use the updated theme.

https://github.com/flutter/flutter/assets/48603081/2f1ebe74-e7d5-4ef3-b97c-a741c3d68964

### Expected Results

Similar to `PopupMenuButton`, the theme should be located in the search view so that when the platform brightness is updated and the search view is rebuilt it can use the updated theme.

![search_view drawio](https://github.com/flutter/flutter/assets/48603081/4e48c0cb-a558-4de6-9865-5f51981a343f)

https://github.com/flutter/flutter/assets/48603081/d8d85982-c661-4cac-83e8-0488b1d93daf

However, the search view's context cannot access local themes so I added support for `InheritedTheme`, which fixes the local. theme issue for both the search view and widgets inside the search view.

### When using local themes for the `SearchAnchor`'s search view and widgets inside the view.

Support for FFI calls with `@Native external` functions through Native assets on Windows. This enables bundling native code without any build-system boilerplate code.

For more info see:

* https://github.com/flutter/flutter/issues/129757

### Implementation details for Windows.

Mainly follows the design of https://github.com/flutter/flutter/pull/134031.

Specifically for Windows in this PR is the logic for finding the compiler `cl.exe` and environment variables that contain the paths to the Windows headers `vcvars.bat` based on `vswhere.exe`.

Resolves #81831.

The PR improves the `config` command in below ways:
- Does not print the settings in usages or other options.
- Adds the `--list` flag to print the full settings list.
- Separates usages for settings and analytics.
- Prints the restart tip when clearing features.

Reverts flutter/flutter#135255

This broke Google Testing, and requires an internal patch before relanding.

[documentation] remove repeated "For example," in RenderSliverEdgeInsetsPadding documentation (#135297)

There was a repeated "For example," in the documentation of `RenderSliverEdgeInsetsPadding`. This PR fix this.

Fixes https://github.com/flutter/flutter/issues/135461

Fixes https://github.com/flutter/flutter/issues/133089

This allows more than one ParentDataWidget to write to the ParentData of a child render object. Previously only one was allowed. There are some rules though:
1. Only one of a given type of `ParentDataWidget` can write to the `ParentData` of a given child.
  a. For example, 2 `Positioned` widgets wrapping a child of a `Stack` would not be allowed, as only one of type `Positioned` can contribute data.

2. The type of `ParentData` **must** be compatible with all of the `ParentDataWidget`s that want to contribute data.
  a. For example, `TwoDimensionalViewportParentData` mixes in the `KeepAliveParentDataMixin`. So the `ParentData` of a given child would be compatible with the `KeepAlive` `ParentDataWidget`, as well as another `ParentDataWidget` that writes `TwoDimensionalViewportParentData` (or a subclass of `TwoDimensionalViewportParentData` - This was the motivation for this change, where a `ParentDataWidget` is being used in `TableView` with the parent data type being a subclass of `TwoDimensionalViewportParentData`.)
