uniapp自定义状态栏在真机运行中undefined

h5预览没问题，打包app和真机预览就会出问题

<u-navbar style="border: 1px solid ;"
          :back-text="orgName"
          :back-icon-name="isShowOrgList ? 'arrow-up' : 'arrow-down'"
          back-icon-color="#fff"
          back-icon-size="30"
          :back-text-style="{
              color: '#fff',
              fontWeight: '700',
              fontSize: 32+'rpx'
          }"
          :custom-back="() => isShowOrgList = !isShowOrgList"
          :background= "{ background: 'linear-gradient(180deg, #7DB2FD 0%, #4395FF 100%)' }"
        >
            <view slot="right" class="u-p-r-30 u-relative" @click="$to.navigateTo('/pages/index/tips/tips')">
                <image src="/static/xiaoxi.svg" style="width: 42rpx;" mode="widthFix"></image>
                <u-badge type="error" count="0" :offset="[-10, 10]" size="mini"></u-badge>
            </view>
        </u-navbar>
        <xInputSelect
          class="org_select_wrap"
          @setName="setName"
          :isShowContent.sync="isShowOrgList"
          :valueList="orgList"
          :style="{width: 12 + 'em'}"
        ></xInputSelect>

这个应该是数据问题，这个值是怎么赋的
