Fixes#135402
Add fallback logic for a different format of java version output and handle no patch versions.
Add tests for new logic output to prevent regressions.
Part of https://github.com/flutter/flutter/issues/130277
Without this, if a user runs an app that has plugins that call method channels with the `preview` device, the app will build successfully, however, they will get a runtime error when their dart code tries to call the method channel that does not exist in the native build (which was pre-built and thus does not include the plugin code).
This change adds a validation when injecting plugins that will tool exit if the device-id is `preview` and their project contains plugins with method channels.
Pin the dependencies from dart-lang/native to a specific version during testing (rather than having them auto-upgrade during pub resolution). This will prevent tests using the template to start failing if a bad version is published to pub.
Closes: https://github.com/flutter/flutter/issues/137418
Also bumps dep in flutter_tools.

Original Description:
Adds support for Android 34 in the following ways:
- Bumps integration tests compile SDK versions 33 --> 34
- Bumps template compile SDK version 33 --> 34
- Also changes deprecated `compileSdkVersion` to `compileSdk`

Fixes https://github.com/flutter/flutter/issues/130808. Short context is that the migration guide doesn't help when a user has a newer java version than 17, and this tells them how to fix the error in that situation.
This is an alternative to https://github.com/flutter/flutter/pull/131354, because I think it is a bad idea to introduce branching in how we handle this error with some specialized regexp.
Analyzer's dependency on autosnapshotting causes issues.
Because every version of integration_test from sdk depends on leak_tracker from hosted and autosnapshotting depends on leak_tracker from path, integration_test from sdk is forbidden.
So, because autosnapshotting depends on integration_test from sdk, version solving failed.
Relands #136851, which was rolled back in #137121
package:coverage has been rolled, so the breakages should be fixed.
Also, in this reland I've changed the `coverableLineCache` parameter to
be optional, which is safer.
## Description
This PR adds a `nonce` parameter to flutter.js' `loadEntrypoint` method.
When set, loadEntrypoint will add a `nonce` attribute to the `main.dart.js` script tag, which allows Flutter to run in environments slightly more restricted by CSP; those that don't add `'self'` as a valid source for `script-src`.
----
### CSP directive
After this change, the CSP directive for a Flutter Web index.html can be:
```
script-src 'nonce-YOUR_NONCE_VALUE' 'wasm-unsafe-eval';
font-src https://fonts.gstatic.com;
style-src 'nonce-YOUR_NONCE_VALUE';
```
When CSP is set via a `meta` tag (like in the test accompanying this change), and to use a service worker, the CSP needs an additional directive: [`worker-src 'self';`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/worker-src)
When CSP set via response headers, the CSP that applies to `flutter_service_worker.js` is determined by its response headers. See **Web Workers API > [Content security policy](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers#content_security_policy)** in MDN.)
----
### Initialization
If the CSP is set to disallow `script-src 'self'`, a nonce needs to also be passed to `loadEntrypoint`:
```javascript
_flutter.loader.loadEntrypoint({
nonce: 'SOME_NONCE',
onEntrypointLoaded: (engineInitializer) async {
const appRunner = await engineInitializer.initializeEngine({
nonce: 'SOME_NONCE',
});
appRunner.runApp();
},
});
```
(`nonce` shows twice for now, because the entrypoint loader script doesn't have direct access to the `initializeEngine` call.)
----
## Tests
* Added a smoke test to ensure an app configured as described above starts.
## Issues
* Fixes https://github.com/flutter/flutter/issues/126977

Original Description:
Since the original PR that supposedly enabled proguard, it was using the android proguard rules that disable optimizations. See initial PR in [0]
This PR changes the flutter gradle plugin to use the `proguard-android-optimize.txt` (instead of `proguard-android.txt`) which will enable optimizations/shrinking of platform code (i.e. java/kotlin).
For a simple flutter hello world this results in a 25% reduction in the resulting DEX file (`classes.dex` of the APK).

Since the original PR that supposedly enabled proguard, it was using the
android proguard rules that disable optimizations. See initial PR in [0]
This PR changes the flutter gradle plugin to use the
`proguard-android-optimize.txt` (instead of `proguard-android.txt`)
which will enable optimizations/shrinking of platform code (i.e.
java/kotlin).
For a simple flutter hello world this results in a 25% reduction in the
resulting DEX file (`classes.dex` of the APK).
Note for users:
For some users this may result in issues because their java/kotlin code is
now better optimized & tree shaken and thereby symbols may be no longer
available or being obfuscated.
To fix those issues it's best to craft precise proguard rules describing the
extra symbols that are needed by the app (see [1]). But it's also possible to
opt out entirely of optimizations by using the unoptimized proguard rules.
To add custom proguard rules or use the unoptimized android rules, one can
update `android/app/build.gradle`:
```
android {
...
buildTypes {
release {
...
+ proguardFiles(
+ // Not ideal: Disables optimizations by using unoptimized android rules.
+ getDefaultProguardFile("proguard-android.txt"),
+
+ // Better: Have precise keep rules to only keep things that are needed.
+ "custom-rules.pro",
+ )
}
}
}

Alters how `throwToolExit` creates its matcher. This results is an improved description of the matcher.
The mismatch description isn't improved by this, but I writing an entirely custom matcher to fix this isn't ideal either. We can instead mitigate the issue by augmenting the `toString` implementation of `ToolExit` to include the exit code, if it is non-null.
With these changes, the first few lines of output from a test would look like this:
```
Expected: throws <Instance of 'ToolExit'> with `exitCode`: <42> and `message`: contains 'message'
Actual: <Closure: () => Never>
Which: threw ToolExit:<Exit code: 41232. Error: message>
```

Original Description:
One of the reasons gathering coverage information is expensive is that we have to force compile every function in the libraries we're interested in. Without this, functions that haven't been invoked (so haven't been compiled) won't have any line number information, so the coverage tool doesn't know which lines to add to the list of misses. In flutter's case, the test infra spawns many VMs, and each of these needs to recompile all those libraries.
To fix this, we need a way of skipping force compilation for libraries we've already seen in previous tests, without losing the information about which lines in each library are coverable. So I [added](https://github.com/dart-lang/coverage/pull/466) the `coverableLineCache` to `coverage.collect` in package:coverage v1.7.0. This cache starts out empty, but fills up with lists of all the lines that are coverable for every library as coverage is gathered. package:coverage can then tell the VM not to force compile any libraries in this cache (using `getSourceReport`'s `librariesAlreadyCompiled` param). So the first test suite will still have to compile everything, but subsequent test suites will be much faster.
This speeds up coverage collection significantly, for large test suites:
| Running flutter/packages/flutter tests... | Time | Overhead |
| --- | --- | --- |
| without coverage | 8:53 | - |
| with coverage | 20:25 | 130% |
| with `coverableLineCache` | 12:21 | 40% |
