android_system_font_weight

Read Android system font-weight data through two synchronous APIs.

import 'package:android_system_font_weight/android_system_font_weight.dart';

getRawData()

Returns a Map<String, String> containing device information, raw font settings and probe results. Use it to write your own device-specific logic. Results are cached; pass refresh: true to collect again.

final data = AndroidSystemFontWeight.getRawData();
final refreshed = AndroidSystemFontWeight.getRawData(refresh: true);

Non-Android platforms or collection failures return an empty map.

getWght()

Calls getRawData() internally and applies the built-in device policy. Returns a double? in the wght range 100–1000, or null to keep the existing font style. No arguments are required.

final weight = AndroidSystemFontWeight.getWght();

The policy handles OPPO, Xiaomi, vivo and Honor families. Huawei, Samsung, Google and other unsupported devices return null. OPPO has been tested; other supported families still need device validation.

Apply a non-null result with FontVariation('wght', weight) when the font used by Flutter supports the wght axis.
