Description
Steps to reproduce
After upgrading from 3.29.3 to 3.32.1 i have started to see multiple ANRs reports in crashlytics, especially from ListBase.removeWhere or ListBase.firstWhere and more precisely _StringBase._interpolate :
Here is a sample of the StackTrace :
#06 pc 0x3c4048 split_config.arm64_v8a.apk (stub CallBootstrapNative + 16384) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#07 pc 0xde8368 split_config.arm64_v8a.apk (Object.toString [object_patch.dart:29]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#08 pc 0x3cdbe0 split_config.arm64_v8a.apk (_StringBase._interpolate [string_patch.dart:915]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#09 pc 0x8c733c split_config.arm64_v8a.apk (Folder.uid [folder.dart:8]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#10 pc 0x8d1e18 split_config.arm64_v8a.apk (FolderViewModel._addFoldersForHour.<anonymous closure> [folder_view_model.dart:1093]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#11 pc 0x436280 split_config.arm64_v8a.apk (ListBase._filter [list.dart:293]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#12 pc 0x436174 split_config.arm64_v8a.apk (ListBase.removeWhere [list.dart:281]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
I have another similar trace with DateTime objects :
#02 pc 0x3c4048 split_config.arm64_v8a.apk (stub CallBootstrapNative + 16384) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#03 pc 0xcefc30 split_config.arm64_v8a.apk (DateTime._timeZoneOffsetInSecondsForClampedSeconds [date_patch.dart:21]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#04 pc 0x408930 split_config.arm64_v8a.apk (DateTime._timeZoneOffsetInSeconds [date_patch.dart:510]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#05 pc 0x408e18 split_config.arm64_v8a.apk (DateTime._localDateInUtcMicros [date_patch.dart:324]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#06 pc 0x40898c split_config.arm64_v8a.apk (DateTime._parts [date_patch.dart:255]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#07 pc 0x8d21d0 split_config.arm64_v8a.apk (FolderViewModel._addFoldersForHour.<anonymous closure> [date_patch.dart:290]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
#08 pc 0x6d55a4 split_config.arm64_v8a.apk (ListBase.firstWhere [list.dart:126]) (BuildId: cde83d0668dcde27ccbd75ad4db8f0b2)
But the common part is the ListBase.firstWhere and here this compares millisecondsSinceEpoch values.
In my app of course i am running some algorithms with several for loops within each of them there are ListBase.removeWhere or ListBase.firstWhere called to compare String (the folder.uid which is my object).
The algorithms are 2-3 for loops inside each other and running among maybe 1millions of items.
I am raising an issue because on 3.29.3 there were no issues and suddenly (maybe with a new Dart SDK update) it starts to be slower and generates ANRs events.
Expected results
The app should not be in "ANR" state -> should respond immediately like on 3.29.3.
Actual results
ANRs are occurring

I am current running a sample code to try to reproduce it locally to match my algorithms
