This class is entirely superseded by the application package factory. Only drive and install use it, and removing it from drive will allow use-application-binary support.

Android Studio 4.1 moved the location of the .home file on Windows which is used to located the install directory. This functionality is important because it is how we locate and discover the Android SDK functionality, as well as the appropriate JRE.

All of the network requests from google cloud storage include an x-goog-hash header which contains an MD5 checksum. If present, use to validate that the downloaded binary is valid. This will rule out corrupt files as the cause of getting started crashers in the flutter_tool.

#38980

This does not fully resolve the above issue, because while we can check if the checksum matches what was expected from cloud storage, this A) may not necessarily be present and B) may not match up to what should be uploaded as part of the engine build process.

But when life gives you lemons you hash those lemons using an outdated hashing algorithm.

A change which sped up hot restart locally caused many of the devicelab measures to regress. I think this is because we do not measure when the isolate is actually "ready", so starting a reload or restart prematurely can cause time spent doing initialization to be registered as part of the reload operation.

A fix for this would be to have the framework include some sort of "initialization complete" event ... but it is not clear what the correct trigger would be. Perhaps after the first frame is successfully registered?

(9a3a0dc1 caused the benchmark regression - possibly since we spend less time syncing files now so we start the restart earlier)

Revert "[flutter_tools] reland: fold process resolution logic into the flutter tool (#67957)" (#67968)

This reverts commit bd813879.

According to https://dart.dev/tools/pub/pubspec#name , uppercase is not permitted for package names.

Reland of #67669

The flutter tool has a number of crashes on stable where an ArgumentError is thrown due to the process manager not being able to resolve an executable.

So that we can adjust/modify this logic, fold it into flutter and add some additional logging.
caches the resolved executable per target directory, to avoid repeated look ups.
Instead of throwing an argument error, attempts to run the executable as given if an exact path can't be found
Accept files or symlinks for the executable path.
user where/which to resolve path instead of package:process logic.

Exposes contentPadding property for RadioListTile from its appropriate ListTile.

On every hot reload, the flutter tool must file stat each asset in the bundle. With a large number of assets or a slow file system, this can take 20 - 30 ms. Do this operation while the flutter tool is waiting for a response from the frontend_server.

No tests updated since this is only a timing update. Any difference in behavior will be shown on benchmarks

This reverts commit 10c78c26.

The flutter tool has a number of crashes on stable where an ArgumentError is thrown due to the process manager not being able to resolve an executable. Fold the resolution logic into the tool and use where/which instead of the package:process specific logic.

Fixes #61772

tool exit if there is no file at the path provided when building/running with sksl

Work towards #39925

Currently flutter run will uninstall and reinstall if the initial install fails and the APK was previously installed. Allow drive to share this same logic by moving it into installApp and out of startApp.

This should reduce the occurrence of the error in the devicelab.

This failure has been happening for a while but was covered by the overly broad catch. Removing that revealed that newer intellij versions have a different plugins file. The tool still can't find the file, but it won't crash now

Fixes #67918

Just another nnbd conversion PR.
