nativeBuildPlatforms function
Platforms under flutter.plugin.platforms that build the engine themselves
(ffiPlugin: true or a pluginClass:) — the ones that double-bundle with a
code asset. Ignores comment lines; web has no native build.
Implementation
List<String> nativeBuildPlatforms(String pubspecContent) {
final out = <String>[];
for (final plat in const ['android', 'ios', 'macos', 'windows', 'linux']) {
final block = _pubspecBlock(pubspecContent, plat);
if (block == null) continue;
final live = block.split('\n').where((l) => !l.trimLeft().startsWith('#')).join('\n');
if (RegExp(r'ffiPlugin:\s*true').hasMatch(live) || RegExp(r'pluginClass:\s*\S').hasMatch(live)) {
out.add(plat);
}
}
return out;
}
