How to Fix White Space Issue in mailto Links with Flutter's url_launcher

When developing Flutter applications, you may come across various challenges, particularly when integrating features like sending emails through the mailto scheme. One common issue is how white spaces in the email body get converted into plus signs (+ ). This can lead to confusing and unattractive email formatting when your users click on an email link. Let's explore how to resolve this problem effectively.

Understanding the issue

When using the url_launcher package in Flutter to create a mailto link, you might have set your email body and subject as query parameters. Here's a simplified example of how this is typically done:

While this code is syntactically correct, it leads to an unwanted result: the email body is converted to this+ is+ sample+ text. This occurs because spaces in URLs are encoded as plus signs when using query parameters. This is not the desired format when composing an email.

The Solution

Fortunately, there’s a straightforward solution to this white space problem. Instead of using queryParameters, you can use the query property in the Uri constructor. This approach allows you to set the email body and subject more directly without changing the spacing.

Step-by-Step Instructions

To fix the issue, follow these steps:

Replace queryParameters with query: Instead of defining your parameters with queryParameters, use a string directly in the query field.

Format your query: Make sure your query is formatted correctly to ensure clarity and functionality.

Here is the revised implementation:

Conclusion

By using the query property instead of queryParameters, you can create cleaner and correctly formatted email bodies in your Flutter applications. This small change can make a significant difference in how users perceive your app's professionalism and reliability. Next time you're setting up an email link through mailto, remember this simple trick to handle white spaces effectively!
