TextScaler' not found

[mauricev]

When building on iOS with 0.65.0, I get

Error (Xcode): ../../../../.pub-cache/hosted/pub.dev/fl_chart-0.65.0/lib/src/chart/bar_chart/bar_chart_renderer.dart:42:5: Error: Type 'TextScaler' not found.

0.64.0 doesn’t have this error.

the above issue is not happening in 0.64.0 version

TextScaler was introduced in Flutter 3.16.0.
Either upgrade you Flutter SDK to 3.16.0 up or use the previous 0.64.0 version.
