Passing props from child to parent Vuejs - vue.js

Question

I have this child component called BaseCardAnnotationOption
<template>
<v-card>
<v-card-title class="text-h5 text-center indigo darken-1 lighten-2">
<slot name="title"> </slot>
</v-card-title>
<v-card-text>
<v-checkbox
v-model="includeAnnotations1"
label="Include Annotations"
#change="deselectDisabled()"
></v-checkbox>
<v-radio-group class="mt-0 ml-12" v-model="annotationOption1">
<v-radio
:value="embedIntoImage"
label="Embedded Into Image"
:disabled="includeAnnotations1 === false"
></v-radio>
<v-radio
:value="burnIntoImage"
label="Burn Into Image"
:disabled="includeAnnotations1 === false"
></v-radio>
<v-checkbox
class="mt-0 ml-8"
v-model="maintainColor1"
label="Maintain Annotation Color "
:disabled="annotationOption1 === 0 || includeAnnotations1 === false"
></v-checkbox>
</v-radio-group>
<v-checkbox
class="mt-0"
v-model="burnReduction1"
label="Burn Reduction"
></v-checkbox>
</v-card-text>
</v-card>
</template>
<script>
export default {
name: "BaseCardAnnotationOption",
data() {
return {
includeAnnotations1: false,
embedIntoImage: null,
burnIntoImage: null,
burnReduction1: false,
maintainColor1: false,
annotationOption1: null
};
},
methods: {
deselectDisabled() {
return this.includeAnnotations1 === false
? ((this.annotationOption1 = null), (this.maintainColor1 = false))
: ((this.annotationOption1 = 0), (this.maintainColor1 = false));
}
}
};
</script>
<style scoped></style>
And i am using it in another parent component named viewer like this
<base-card-annotation-option>
<template v-slot:title>
Print Document
</template>
</base-card-annotation-option>
Now i want to use this function in Viewer(parent) which requires data that has been
declared in BaseCardAnnotationOption(child) as shown below
<base-tooltip-button
#click="
onPrintFile(
document,
asPdf,
includeAnnotations1,
annotationOption1,
burnReduction1,
maintainColor1
)
"
>
Print
<template v-slot:toolTip>
Print
</template>
</base-tooltip-button>
So basically some data has been declared in child which i want to send to parent . How can that be achieved ? Thanks
