Why this matters
Using for elements instead of Map.fromIterable improves readability and allows for compiler optimizations, making the code more performant.
for Elements Over Map.fromIterableUse for elements inside map literals instead of Map.fromIterable to improve readability and allow better compiler optimizations.

Side-by-side examples engineers can pattern-match during review.
Map<String, int>.fromIterable(
[1, 2, 3],
key: (v) => 'The value is $v',
value: (v) => v,
);{
for (final v in [1, 2, 3])
'The value is $v': v
}From the same buckets as this rule.
All static JS/CSS/font/image files MUST use content-hashed filenames (e.g., app.9c1a7b.js) and be served with "Cache-Control: public, max-age=31536000, immutable". HTML and other non-fingerprinted documents MUST be served with "Cache-Control: no-cache" (or equivalent) to enable conditional revalidation.
