The uniapp date picker cannot select a date on the phone

The date picker was written like this before:

<picker mode="date" :value="date" start="" end="" @change="bindDateChange">
        <view class="picker">
              <text class="tishi2">{ {date}}</text>
         </view>
   </picker>

The date cannot be selected when Android is packaged and installed on the mobile phone. The reason is that the attribute values ​​​​of start and end are not set. Setting these two values ​​​​can be selected:

<template>
	<view class="container">
		<picker mode="date" :value="date" :start="startDate" :end="endDate" @change="bindDateChange">
			<text>{
   
   {date}}</text>
		</picker>

	</view>
</template>

<script>
	
	function getDate(type) {
		const date = new Date();
	
		let year = date.getFullYear();
		let month = date.getMonth() + 1;
		let day = date.getDate();
	
		if (type === 'start') {
			year = year - 100;
		} else if (type === 'end') {
			year = year + 100;
		}
		month = month > 9 ? month : '0' + month;;
		day = day > 9 ? day : '0' + day;
	
		return `${year}-${month}-${day}`;
	}
	
	
	export default {
		data() {
			return {
				
				date: getDate({
					format: true
				}),
                startDate:getDate('start'),
				endDate:getDate('end'),
				
			}
		},
		methods: {
			//日期选择
			bindDateChange: function(e) {
				this.date = e.detail.value
			}
		},
		onLoad() {
			
		}
	}
</script>

<style>
