### Code Reproduction
```escapeVCard(text: string | undefined): string {
if (!text) return '';

return text
.replace(/\\/g, '\\\\')
.replace(/\n/g, '\\n')
.replace(/,/g, '\\,')
.replace(/;/g, '\\;');
}
toAsciiFileName(s: string) {
return (s || '')
.normalize('NFD')
.replace(/[\u0300-\u036f]/g, '')
.replace(/[^a-zA-Z0-9_-]/g, '_');
}

generateVCard(contact: {
firstName: string;
lastName: string;
phone?: string;
email?: string;
organization?: string;
address?: string;
website?: string;
}): string {
const lines: string[] = [];
lines.push('BEGIN:VCARD');
lines.push('VERSION:3.0');
const lastName = this.escapeVCard(contact.lastName);
const firstName = this.escapeVCard(contact.firstName);
lines.push(`N:${lastName};${firstName};;;`);
lines.push(`FN:${firstName} ${lastName}`.trim());
if (contact.organization) {
lines.push(`ORG:${this.escapeVCard(contact.organization)}`);
}
if (contact.phone) {
lines.push(`TEL;TYPE=CELL:${this.escapeVCard(contact.phone)}`);
}
if (contact.email) {
lines.push(`EMAIL;TYPE=INTERNET:${this.escapeVCard(contact.email)}`);
}
if (contact.address) {
const addressParts = contact.address.split(';');
const escapedParts = addressParts.map(part => this.escapeVCard(part));
lines.push(`ADR;TYPE=HOME:;;${escapedParts.join(';')}`);
}
if (contact.website) {
lines.push(`URL:${this.escapeVCard(contact.website)}`);
}
lines.push('END:VCARD');
return lines.join('\r\n') + '\r\n';
}

async contactShare(): Promise {
if (!this.vcardValue) return;
const safeFirst = this.toAsciiFileName(this.firstname);
const safeLast = this.toAsciiFileName(this.lastname);
const fileName = `${safeFirst || 'Contact'}_${safeLast || 'VCard'}.vcf`;

const dir = Directory.Documents;
await Filesystem.writeFile({path: fileName, data: this.vcardValue, directory: dir, encoding: Encoding.UTF8});

const {uri} = await Filesystem.getUri({directory: dir, path: fileName});

await Share.share({
title: `${this.firstname} ${this.lastname}`.trim(),
dialogTitle: 'Share contact',
files: [uri],
});
