Vue.js : Property or method is not defined on the instance but referenced during render

I have

<template>
    <div class="dashboard">
        <Navbar />
        <MainPanel :title="Dashboard" :icon="dasboard" />
    </div>
</template>

<script>
import MainPanel from '../../components/MainPanel'
import Navbar from '../../components/Navbar'

export default {
    name: 'Dashboard',
    components: {
        Navbar,
        MainPanel
    }
}
</script>

As you can see, I'm trying to reuse my MainPanel component.

MainPanel

<template>
    <v-container fluid class="my-5">
        <v-row>
            <v-flex col-xs-12>
                <v-card elevation="2" class="pb-15">
                    <v-flex xs12 class="text-center">
                        <v-card-title>
                            <v-btn dark text color="black">
                                <v-icon right class="mr-2">{{ icon }}</v-icon>
                                <span>{{ title }}</span>
                            </v-btn>
                        </v-card-title>
                    </v-flex>
                </v-card>
            </v-flex>
        </v-row>
    </v-container>
</template>
<script>
export default {
    name: 'MainPanel',
    props: {
        icon: String,
        title: String
    },
    data() {
        return {
            icon: '',
            title: ''
        }
    }
}
</script>
<style lang=""></style>

In the console, I kept getting this error

[Vue warn]: Property or method "dasboard" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

Can someone please give me some hints ?

It seems a very simple mistake:

:title="Dashboard"

in Vue using a colon (:) to prepend a prop or an attribute on a component, will use a property defined or in props or in data. While if you use title="dashboard" you'll actually pass a string, that is what you want
