Sending messages #
Messages are sent using [MessageClient], which comes preconfigured under [MailgunClient.message].
To send a message using the [MessageClient.send] method, you first configure parameters through [MessageParams].
It accepts all parameters that are listed in the Mailgun API docs, and will also handle passing the parameters to a [http.MultipartRequest] object.
The actual content of the email is under [MessageParams.content] and is an instance of [MessageContent], configured using one of the factory constructors:

[MessageContent.text] - adds the content under request.fields['text']
[MessageContent.html] - adds the content under request.fields['html'], and
[MessageContent.template] - lets you send an email using a configured template. It has two parameters; one for the template name and one for a map of the different variables that you want to use.

Examples

Plaintext

var messageClient = client.message
var params = MessageParams(
from: from,
to: to,
subject: 'email',
content: MessageContent.text('hello'),
)
var response = await messageClient.send(params)
copied to clipboard

HTML

var messageClient = client.message
var params = MessageParams(
from: from,
to: to,
subject: 'email',
content: MessageContent.html('<h1>hello</h1>'),
)
var response = await messageClient.send(params)
copied to clipboard

Template

var messageClient = client.message
var params = MessageParams(
from: from,
to: to,
subject: 'email',
content: MessageContent.template('mytemplate', {'var1': 'val1'}),
)
var response = await messageClient.send(params)
copied to clipboard
[MessageParams] also accepts attachments as a list of [io.File] objects:
var messageClient = client.message
var params = MessageParams(
from: from,
to: to,
subject: 'email',
content: MessageContent.text('hello'),
attachments: [File('$path/myfile.txt')],
)
var response = await messageClient.send(params)
copied to clipboard
If you can't find the parameter you're looking for it might be configurable under [MessageParams.options] - as an instance of [MessageOptions]:
var params = MessageParams(
from: from,
to: to,
subject: 'email',
content: MessageContent.text('hello'),
options: MessageOptions(
tracking: true,
requireTLS: false,
customHeaders: {
'My-Header': 'myheadervalue'
},
dkim: false,
testMode: true
),
)
copied to clipboard
[MessageOptions] automatically parses the keys of [MessageOptions.customHeaders] to h:X-$key, and [MessageOptions.customVars] to v:$key, so unless you want to you don't need to include the prefix.
Response #
Responses from any clients will be instances of the [Response] class.
The response contains two methods:

[Response.ok]returns a boolean indicating a successful response, and
[Response.status] returns an instance of [ResponseStatus], which contains the statuscode under [ResponseStatus.code] as well as the reasonphrase under [ResponseStatus.reason].

You can also directly access both of these from [Response.statusCode], and [Response.reasonPhrase] respectively.
The body is found in [Response.body]. It parses both text responses and json responses into [Map<String, String>] and supports both [http.Response]s and [http.StreamedResponse]s. [Response.body] returns a [Future<Map<String, dynamic>>] to be able to read bytes from the body of an [http.StreamedResponse].
Text bodies are added under Response.body['message'].
var response = await client.send(params)
if(!response.ok()){
//handle error
print(response.reasonPhrase)
} else {
var body = await response.body
print(body['message'])
// handle result
}
copied to clipboard
Plan type safety #
In order to mitigate the risk of errors, the [MessageOptions] class checks if you have the required Mailgun plan to use certain options.
From what I could find in their documentation there are two options that aren't available on plans other than scale:

o: deliverytime-optimize-period, and
o: timezone-localize

To use these options, when configuring your parameters, under [MessageParams.options], set [MessageOptions.plan] to [PlanType.scale].
