Steps to reproduce

Flutter method channel crash in background 1.19% in appstore, 6.62‱ in tester environment, from the stacktrace I could know which feature cause this issue, does some one known this issue, or it's a bug in flutter sdk?

shell/platform/darwin/common/framework/Source/FlutterChannels.mm:
  205  @implementation FlutterMethodCall
  206: + (instancetype)methodCallWithMethodName:(NSString*)method arguments:(id)arguments { // it's the crash line

Hello @LongXiangGuo, Thanks for filing the issue. You seem to be using very old version of flutter, Is it possible for you to upgrade to latest stable and release and see if the crash reproduces? Is the crash device specific?

Hello @LongXiangGuo, Thanks for filing the issue. You seem to be using very old version of flutter, Is it possible for you to upgrade to latest stable and release and see if the crash reproduces? Is the crash device specific?

From the analytics portal I have got this informs. Unfortunately, currently I have not reproduce yet.
System version: Both are concentrated on iOS 18 and iOS 17.
100.00% of the crashed thread names are com. apple. main thread;
95.12% of crashes have available memory greater than 500M, which seems unrelated to insufficient physical memory;
76.19% of crashes have a usage duration greater than 60 minutes, and triggering crashes may require the application to be used for a long time
100.00% of crashed pages are: FlutterViewController；
99.95% of crashes occur in the background

We've modernized the memory semantics around this callsite since this older version of the engine was released. This won't be actionable until we get an updated crash log on a newer version of Flutter. Can you update your version of Flutter and see if the crash is still happening?

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
