API documentation cleanup #108500

Hixie · 2022-07-28T00:39:24Z

Enable asserst when running analyze_snippet_code.dart
Revamp analyze_snippet_code.dart to actually analyze all code snippets.
Add a full example for SliverOpacity.
Export src/cupertino/debug.dart which we somehow had missed.
Fix a zillion minor errors in API docs and especially API sample code.

Two newlinews here? lol

good catch. fixed.

in ScrollPhysics you added ... without a newline.

removed the leading/trailing blank lines here

Should we add num?

added, but i wouldn't encourage anyone to write code using num.

dev/bots/analyze_snippet_code.dart

Should we add const and extension ?

This regexp will not match top level functions or mutable variables.

Added extension, though hopefully no examples even use that.

const is intentionally not here because it's used when showing examples of Widgets, which are expressions.

Top-level functions are handled by _maybeFunctionDeclarationRegExp.

Mutable variables are hard to recognize. We never use var because of the analysis options. Generally they end up being treated as statements, which seems to work for our current examples.

dev/bots/analyze_snippet_code.dart

It looks like we can refactor this to:

Suggested change

if (line.startsWith('// // ignore_for_file: ')) {

final _Line newLine = _Line(

line: lineNumber,

indent: 3,

code: line.substring(3),

);

ignorePreambleLinesOnly.add(newLine);

preambleLines.add(newLine);

} else {

preambleLines.add(_Line(line: lineNumber, indent: 3, code: line.substring(3)));

}

final _Line newLine = _Line(line: lineNumber, indent: 3, code: line.substring(3));

if (line.startsWith('// ignore_for_file: ')) {

ignorePreambleLinesOnly.add(newLine);

}

preambleLines.add(newLine);

a14n · 2022-07-28T09:04:08Z

dev/bots/analyze_snippet_code.dart

Suggested change

if (preamble.isNotEmpty)

...preamble,

if (preamble.isNotEmpty)

const _Line.generated(), // blank line

if (preamble.isNotEmpty) ...[

...preamble,

const _Line.generated(), // blank line

],

i considered doing that but isn't that less efficient? now you're building a list just to inject it back into another list, rather than just evaluating a boolean variable twice.

a14n · 2022-07-28T09:09:47Z

dev/bots/analyze_snippet_code.dart

We can use collection-if and collection-for:

final List<_Line> codeLines = <_Line>[ if (prefix != null) _Line.generated(code: prefix), for (int i = 0; i < code.length; ++i) _Line( code: code[i], line: firstLine.line + i, indent: firstLine.indent, ), if (postfix != null) _Line.generated(code: postfix), ];

unnecessary wrap

PR updated per comments, thanks for the reviews!

goderbauer

Thanks for cleaning this up!!!

packages/flutter/lib/src/material/calendar_date_picker.dart

I would expect that the alignment here will be off when these are rendered with a variable-width font on https://api.flutter.dev/?

(or does dartdoc have a special feature that I am not aware off and these will continue to render with a fixed-width font even without the ```?)

I have the same concern for many other places in this PR...

The four space indent triggers monospace font.

goderbauer · 2022-08-02T00:17:43Z

packages/flutter/lib/src/widgets/animated_list.dart

Is ... special cased somehow? Otherwise, shouldn't this be

Suggested change

/// ...

/// // ...

Now that I read the doc in analyze_snippet_code.dart, I see that it is special cased. I would argue that that isn't necessary and instead the ... should just be added as a comment. Has the added benefit that if I copy this snippet into my own code, I don't get a bunch of analyzer warnings on this line. Everywhere else (e.g. // continuing from previous example...) these are also used in comments.

yeah, seems reasonable, i'll remove this feature.

(Or more to the point, make it require // .... The feature itself is still useful, it adds an ignore.)

goderbauer · 2022-08-02T00:18:58Z

packages/flutter/lib/src/widgets/basic.dart

We should somewhere document what strings with special meaning you can use so we can point people to it in code reviews. I wonder, what would be a good place for that.

I see that they are documented in analyze_snippet_code.dart.

goderbauer · 2022-08-02T00:25:04Z

dev/bots/analyze_snippet_code.dart

Otherwise, they are... ?

technically this bullet point continues the sentence started by "Such snippets:", though admittedly by this point in the text the reader has probably forgotten this. :-)

goderbauer · 2022-08-02T00:30:58Z

dev/bots/analyze_snippet_code.dart

I wonder if we should give these control comments a common prefix. It would indicate to the reader that these comments are actually load-bearing. Also, if I want to author a new example and look at an existing one it would give me something to search for to understand what other control comments are available.

On the other hand, it my hinder the reading flow of these examples...

Just a thought, not feeling super-strongly about this either way.

yeah i feel super constrained here because the most important result is that the examples flow well for the developers.
on the other hand, these load-bearing comments are so magical, ugh.

I've added a message to the snippet analyzer's output that just points right at the docs, FWIW. Dunno how much it'll help.

Hixie · 2022-08-03T23:10:36Z

Landed fixes for the dev/bots/test tests.

See flutter/flutter#108500

This depends on flutter/engine#35146 rolling into the framework.
