compileSdkVersion 34

[nickesk]

#466 broke apps with compileSdkVersion less than 34. That was released as a patch (8.2.2 => 8.2.3), which is not backwards-compatible. Please revert this change.

Note that #467 only reverted the minSdkVersion change which is necessary but not sufficient to prevent breaking backwards-compatibility.

I got build error today. I just updated flutter/dart SDK to latest version, and hit flutter pub get. I tried cleaning pub cache, build and also downgrading flutter/dart SDK to old one. but not luck.

I noticed that fluttertoast's minSdkVersion changes since 8.2.3.

I also checked what was changed on Flutter SDK, minSdkVersion stays 19.

According to build error log, seems there are two options to make it TEMPORALY.

1. Change minSdkVersion property from flutter.minSdkVersion to 22 in build.gradle[app]
2. Fix a version of fluttertoast 8.2.2.

Both are not good solution.

Anyone who suffers get build error like below, please stay 8.2.2 and I wish this issue resolved ASAP.
