      Support conditional bundling of assets based on `--flavor` (#132985) · 016eb851
      Andrew Kolos authored 
      Provides support for conditional bundling of assets through the existing `--flavor` option for `flutter build` and `flutter run`. Closes https://github.com/flutter/flutter/issues/21682. Resolves https://github.com/flutter/flutter/issues/136092

## Change
Within the `assets` section pubspec.yaml, the user can now specify one or more `flavors` that an asset belongs to. Consider this example:

```yaml
# pubspec.yaml
flutter:
  assets:
    - assets/normal-asset.png
    - path: assets/vanilla/ice-cream.png
      flavors: 
        - vanilla
    - path: assets/strawberry/ice-cream.png
      flavors:
        - strawberry
```

With this pubspec,
* `flutter run --flavor vanilla` will not include `assets/strawberry/ice-cream.png` in the build output.
* `flutter run --flavor strawberry` will not include `assets/vanilla/ice-cream.png`.
* `flutter run` will only include `assets/normal-asset.png`.

## Open questions

* Should this be supported for all platforms, or should this change be limited to ones with documented `--flavor` support (Android, iOS, and (implicitly) MacOS)? This PR currently only enables this feature for officially supported platforms.

## Design thoughts, what this PR does not do, etc.

### This does not provide an automatic mapping/resolution of asset keys/paths to others based on flavor at runtime.

The implementation in this PR represents a simplest approach. Notably, it does not give Flutter the ability to dynamically choose an asset based on flavor using a single asset key. For example, one can't use `Image.asset('config.json')` to dynamically choose between different "flavors" of `config.json` (such as `dev-flavor/config.json` or `prod-flavor/config.json`). However, a user could always implement such a mechanism in their project or in a library by examining the flavor at runtime.

### When multiple entries affect the same file and 1) at least one of these entries have a `flavors` list provided and 2) these lists are not equivalent, we always consider the manifest to be ambiguous and will throw a `ToolExit`. 

<details>
For example, these manifests would all be considered ambiguous:

```yaml
assets:
  - assets/
  - path: assets/vanilla.png
    flavors: 
      - vanilla

assets:
  - path: assets/vanilla/
    flavors: 
      - vanilla
  - path: assets/vanilla/cherry.png
     flavor:
      - cherry

# Thinking towards the future where we might add glob/regex support and more conditions other than flavor:
assets:
  - path: assets/vanilla/**
    flavors:
      - vanilla
  - path: assets/**/ios/**
    platforms: 
       - ios

# Ambiguous in the case of assets like "assets/vanilla/ios/icon.svg" since we 
# don't know if flavor `vanilla` and platform `ios` should be combined using or-logic or and-logic.
```

See [this review comment thread](https://github.com/flutter/flutter/pull/132985#discussion_r1381909942) for the full story on how I arrived at this decision.
</details>

### This does not support Android's multidimensional flavors feature (in an intuitive way)

<details>

Conder this excerpt from a Flutter project's android/app/build.gradle file:

```groovy
android {
    // ...

    flavorDimensions "mode", "api"

    productFlavors {
        free {
            dimension "mode"
            applicationIdSuffix ".free"
        }

        premium {
            dimension "mode"
            applicationIdSuffix ".premium"
        }

        minApi23 {
            dimension "api"
            versionNameSuffix "-minApi23"
        }

        minApi21 {
            dimension "api"
            versionNameSuffix "-minApi21"
        }
    }
}
```

In this setup, the following values are valid `--flavor` are valid `freeMinApi21`, `freeMinApi23`, `premiumMinApi21`, and `premiumMinApi23`. We call these values "flavor combinations". Consider the following from the Android documentation[^1]:

> In addition to the source set directories you can create for each individual product flavor and build variant, you can also create source set directories for each combination of product flavors. For example, you can create and add Java sources to the src/demoMinApi24/java/ directory, and Gradle uses those sources only when building a variant that combines those two product flavors.
> 
> Source sets you create for product flavor combinations have a higher priority than source sets that belong to each individual product flavor. To learn more about source sets and how Gradle merges resources, read the section about how to [create source sets](https://developer.android.com/build/build-variants#sourcesets).

This feature will not behave in this way. If a user utilizes this feature and also Android's multidimensional flavors feature, they will have to list out all flavor combinations that contain the flavor they want to limit an asset to:

```yaml
assets:
  - assets/free/
    flavors:
      - freeMinApi21
      - freeMinApi23
```

This is mostly due to a technical limitation in the hot-reload feature of `flutter run`. During a hot reload, the tool will try to update the asset bundle on the device, but the tool does not know the flavors contained within the flavor combination (that the user passes to `--flavor`). Gradle is the source of truth of what flavors were involved in the build, and `flutter run` currently does not access to that information since it's an implementation detail of the build process. We could bubble up this information, but it would require a nontrivial amount of engineering work, and it's unclear how desired this functionality is. It might not be worth implementing.

See https://flutter.dev/go/flavor-specific-assets for the (outdated) design document.

      Introduce `exitDuration` to Tooltip for mouse pointer devices (#138321) · 3c422dd7
      Jasper van Riet authored 
      This PR introduces a new property `exitDuration` to Tooltip, the counterpart to `waitDuration`. The need for this is shown by #136586. This changes the behaviour of `showDuration` on mouse pointer devices. This is because the use cases for the current behaviour on touch screen devices vs mouse pointer devices is fundamentally different.

<details>
<summary>Demo: tooltip with showDuration set</summary>

Tooltip disappears after 100 ms when moving away the mouse. Tooltip will not disappear when hovered.

https://github.com/flutter/flutter/assets/5138348/81d36dc9-78e0-4723-a84b-2552843ee181

</details>

Currently, when `showDuration` is set, this adjusts the time it takes for the tooltip to hide _after_ a mouse pointer has left the tooltip. This is not the same use case as its effect on touch screen devices, where it dictates how long the tooltip stays on screen after a long press. That is needed because the tooltip takes up screen space and there is not an intuitive way to hide it, whereas when using a mouse users expect to simply have to hover somewhere else. Having the tooltip stay around will look broken.

Thus, this PR splits the two use cases. `showDuration` no longer affects mouse pointer devices at all*. There is a precedent for such mouse pointer-only behaviour in `waitDuration`. Instead, I have split up the two use cases and created the new property `exitDuration`, which will still allow for tweaking the time it takes for the tooltip to hide after the user has moved their mouse pointer somewhere else.

*Note: Should `showDuration` affect [this line](https://github.com/flutter/flutter/blob/e33d4b86270e3c012ba13d68d6e90f2eabc4912b/packages/flutter/lib/src/material/tooltip.dart#L610)?

Fixes #136586.

Note: I noticed that when I made the change, no tests were broken. Hopefully, the tests added here help that in the future. I also noticed that in the _existing_ tests, the `waitDuration` tests contain assertions that implicate that it is the role of `waitDuration` to change this behaviour, but that's not currently (nor in the new behaviour) true, so I have fixed those tests.
