Open Mail App Flutter

A boring but accurate name.

This library provides the ability to query the device for installed email apps and open those apps.

If you just want to compose an email or open any app with a mailto: link, you are looking for url_launcher.

Why

While url_launcher can help you compose an email or open the default email app, it doesn't give you control over which is opened and it doesn't tell you what is available on the device. This is especially a problem on iOS where only the default Mail app will be opened, even if the user prefers a different app.

Setup

iOS requires you to list the URL schemes you would like to query in the Info.plist file.

<key>LSApplicationQueriesSchemes</key>
<array>
<string>googlegmail</string>
<string>x-dispatch</string>
<string>readdle-spark</string>
<string>airmail</string>
<string>ms-outlook</string>
<string>ymail</string>
<string>fastmail</string>
<string>superhuman</string>
<string>protonmail</string>
</array>

Please file issues to add popular email apps you would like to see on iOS. They need to be added to both your app's Info.plist and in the source of this library.

// If no mail apps found, show errorif (!result.didOpen &&!result.canOpen) {
showNoMailAppsDialog(context);
// iOS: if multiple mail apps found, show dialog to select.// There is no native intent/default app system in iOS so// you have to do it yourself.
} elseif (!result.didOpen && result.canOpen) {
showDialog(
context: context,
builder: (_) {
returnMailAppPickerDialog(
mailApps: result.options,
