+    final String stdout = result.stdout as String;
+    final String stderr = result.stderr as String;


Do we need to do any null checks on these? Or can we assume that it will always return an empty string when empty?

No, this will always be either List<int> (if you chose not to encode it) or String https://github.com/dart-lang/sdk/blob/main/sdk/lib/io/process.dart#L525

No, see the other comment

Sgtm, sorry for the double comment

+    expect(result, const ProcessResultMatcher(exitCode: 1));
    expect(result.stderr.toString(), contains('Cannot fit requested classes in a single dex file'));
    expect(result.stderr.toString(), contains('The number of method references in a .dex file cannot exceed 64K.'));


Could we refactor this to use the matcher's stdout and stderr matchers?

Suggested change

expect(result, const ProcessResultMatcher(exitCode: 1));

expect(result.stderr.toString(), contains('Cannot fit requested classes in a single dex file'));

expect(result.stderr.toString(), contains('The number of method references in a .dex file cannot exceed 64K.'));

expect(

result,

const ProcessResultMatcher(

exitCode: 1,

stderrPattern: 'Cannot fit requested classes in a single dex file',

stdoutPattern:

'The number of method references in a .dex file cannot exceed 64K.'));

these are both on stderr though

Ah I was going too fast, makes sense though. LGTM on everything else then

I briefly thought about some kind of API that would allow either a pattern OR Iterable<Pattern> for stdout matchers, but then thought better of it given how confusing the process.stdout API is (it's typed dynamic but is one of String or List<int>
