A conditional value was caught referencing a nonexistent breakpoint.

[shafquat1]

I don't understand how can we replicate the example app in our own code, I am getting this error when trying to do the same. I was previously using 0.2.0 but when I migrated to 1.0.0 I am having these issues. Can anyone help?

This is my debug log:
======== Exception caught by widgets library =======================================================
The following assertion was thrown building Builder(dirty):
A conditional value was caught referencing a nonexistent breakpoint.
ResponsiveValue requires a parent ResponsiveWrapper to reference breakpoints. Add a ResponsiveWrapper or remove breakpoint references.
The relevant error-causing widget was:
MaterialApp MaterialApp:file:///home/lenovo/Aeologic/projects/omgiva/lib/main.dart:141:16
When the exception was thrown, this was the stack:

This is my main.dart file:

ResponsiveBreakpoints.builder(
                  breakpoints: [
                    Breakpoint(start: 0, end: 480, name: MOBILE),
                    Breakpoint(start: 481, end: 1200, name: TABLET),
                    Breakpoint(start: 1201, end: 1600, name: DESKTOP),
                  ],
                  child: MaxWidthBox(
                    // A widget that limits the maximum width.
                    // This is used to create a gutter area on either side of the content.
                    maxWidth: 922,
                    background: Container(color: ColorConstants.lightGrey),
                    child: ResponsiveScaledBox(
                      width:
                          ResponsiveValue<double>(context, conditionalValues: [
                        Condition.equals(name: MOBILE, value: 480),
                        Condition.between(start: 0, end: 481),
                        Condition.equals(name: TABLET, value: 1200),
                        Condition.between(start: 481, end: 922),
                        // There are no conditions for width over 922
                        // because the `maxWidth` is set to 922 via the MaxWidthBox.
                      ]).value,
                      child: _streamChatWidget(child),
                    ),
                  ),
                );

Same issue here, I think 1.0.0 needs some more work

Hello, this error cause by you are using context do not contain ResponsiveWrapper or ResponsiveBreakpoints.
Wrap with Builder will be solve.

ResponsiveBreakpoints.builder(
      breakpoints: [
        Breakpoint(start: 0, end: 480, name: MOBILE),
        Breakpoint(start: 481, end: 1200, name: TABLET),
        Breakpoint(start: 1201, end: 1600, name: DESKTOP),
      ],
      child: MaxWidthBox(
        // A widget that limits the maximum width.
        // This is used to create a gutter area on either side of the content.
        maxWidth: 922,
        background: Container(color: ColorConstants.lightGrey),
        child: Builder(
          builder: (context) {
            return ResponsiveScaledBox(
              width:
              ResponsiveValue<double>(context, conditionalValues: [
                Condition.equals(name: MOBILE, value: 480),
                Condition.between(start: 0, end: 481),
                Condition.equals(name: TABLET, value: 1200),
                Condition.between(start: 481, end: 922),
                // There are no conditions for width over 922
                // because the `maxWidth` is set to 922 via the MaxWidthBox.
              ]).value,
              child: _streamChatWidget(child),
            );
          }
        ),
      ),
    );
