[tool_crash] _TypeError: (#0 FlutterCommand.extractDartDefineConfigJsonMap.<anonymous closure> (package:flutter_tools/src/runner/flutter_command.dart:1402:50)) #128787
Description
Command
flutter run --dart-define-from-file=config/base.json --dart-define-from-file=config/local.json
Steps to Reproduce
- Create a base.json like:
{ "TESTER_EMAIL": null, "TESTER_PASSWORD": null } - Create a local.json like:
{ "TESTER_EMAIL": "some", "TESTER_PASSWORD": "value" } - Run the above command with the two dart define files.
It seems to read the JSON values and fails to convert it because it does not support null values.
I expected that it would support null values by just omitting it from the dart-define.

@wolfenrain actually, is the right thing to do here ignore keys whose value is
null, or to forward thatnull?wolfenrain commentedon Jun 14, 2023
With ignore I did mean to forward it, reading those values using
String.fromEnvironmentalready handles null and non existing values by just falling back to the provides default value[flutter_tools] fix cast error when dart-defines-json file includes n…
