+        _resolveSide(radioTheme.side, activeStates) ??
        BorderSide(
          color: effectiveActiveColor,
          width: 2.0,
          strokeAlign: BorderSide.strokeAlignCenter,
        );
    final BorderSide inactiveSide =
        _resolveSide(widget.side, inactiveStates) ??
+        _resolveSide(radioTheme.side, inactiveStates) ??
        BorderSide(
          color: effectiveInactiveColor,
          width: 2.0,


I couldn't add side to the defaults (like backgroundColor) because it needs effectiveActiveColor and effectiveInactiveColor

@justinmc @chunhtai Any feedback on this PR?

justinmc

Just some small stuff, thanks again for the Radio improvements.

packages/flutter/test/material/radio_theme_test.dart

+
+    // Radio.
+    await tester.pumpWidget(buildRadio());
+    await tester.pumpAndSettle();


Just double checking that this pumpAndSettle is necessary?

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

  ///  * [WidgetState.focused].
  ///  * [WidgetState.disabled].
  ///
  /// If null, then it defaults to a border using the fill color.


Is this no longer true? Now it first falls back to RadioThemeData.side, then defaults to a border using the fill color.

Good catch! I updated the documentation in Fix comment, lerp and pumpAndSettle

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

+      return BorderSide.lerp(BorderSide(width: 0, color: b!.color.withAlpha(0)), b, t);
+    }
+    if (b == null) {
+      return BorderSide.lerp(BorderSide(width: 0, color: a.color.withAlpha(0)), a, t);


Should the order be reversed or am I misunderstanding?

BorderSide.lerp(a, BorderSide(width: 0, color: a.color.withAlpha(0)), t);

If not then maybe my reassignment idea doesn't work here.

No, you are right! I copied this code from other places in the repository, so I think we have a bug at some other places

I can fix the code there, too. Would you want me to include it in this PR or raise a new one?

For reference:

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

Lines 236 to 252 in 5a078b8

// Special case because BorderSide.lerp() doesn't support null arguments

static BorderSide? _lerpSides(BorderSide? a, BorderSide? b, double t) {

if (a == null || b == null) {

return null;

}

if (identical(a, b)) {

return a;

}

if (a is MaterialStateBorderSide) {

a = a.resolve(<WidgetState>{});

}

if (b is MaterialStateBorderSide) {

b = b.resolve(<WidgetState>{});

}

return BorderSide.lerp(a!, b!, t);

}

}

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

Lines 564 to 582 in 5a078b8

// Special case because BorderSide.lerp() doesn't support null arguments.

static BorderSide? _lerpSides(BorderSide? a, BorderSide? b, double t) {

if (a == null && b == null) {

return null;

}

if (a is MaterialStateBorderSide) {

a = a.resolve(<WidgetState>{});

}

if (b is MaterialStateBorderSide) {

b = b.resolve(<WidgetState>{});

}

if (a == null) {

return BorderSide.lerp(BorderSide(width: 0, color: b!.color.withAlpha(0)), b, t);

}

if (b == null) {

return BorderSide.lerp(BorderSide(width: 0, color: a.color.withAlpha(0)), a, t);

}

return BorderSide.lerp(a, b, t);

}

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

Lines 226 to 236 in 5a078b8

// Special case because BorderSide.lerp() doesn't support null arguments

static BorderSide? _lerpSides(BorderSide? a, BorderSide? b, double t) {

if (a == null || b == null) {

return null;

}

if (identical(a, b)) {

return a;

}

return BorderSide.lerp(a, b, t);

}

}

I fixed the one of this PR in Fix comment, lerp and pumpAndSettle

Thanks, that looks good. Are there any remaining that still need to be fixed in a separate PR or did you get them all?

Currently this PR only contains the fix for radio, there are still the 2 other instances mentioned above to fix in a separate PR

+    if (a == null) {
+      return BorderSide.lerp(BorderSide(width: 0, color: b!.color.withAlpha(0)), b, t);
+    }


Nit: I might just reassign a here, but it's up to you.

a ??= BorderSide.lerp(BorderSide(width: 0, color: b!.color.withAlpha(0)), b, t);

I like it :)

I updated the code in Fix comment, lerp and pumpAndSettle

LGTM once remaining comments are resolved
